Symptoms: Recognition, Acknowledgement And Denial

symptom n. an abnormality caused by a disease that is observable in a sick animal
Source: Dictionary of Veterinary Terms: Vet-speak Deciphered for the Non-veterinarian

The above definition points out two important things. A symptom is an abnormality that can be observed.

As far as your dog's health is concerned, this is the most important part of your job. 

You're the one who needs to pick up on such things. Well, of course you know that, that is a no-brainer, isn't it? You would be surprised how often it is not.

Observing doesn't necessarily mean understanding

Roxanne Hawn of Champion of My Heart wrote a great heartfelt article on the subject, Fearful Dog's and Medical Warning Signs. Sometimes we get so used to certain existing abnormalities, such as fear, that it is very easy to miss their medical significance.

If you had a confident dog, who suddenly became fearful, you're likely to take notice. But what if your dog is already fearful?

Your dog might be fearful, he might be quiet, he might be reactive … it is knowing what is normal for your dog that is important.

Knowing what is normal

Knowing what is normal requires truly knowing your dog. Nobody else can do this for you.

Some symptoms are hard to miss because they hit you right in the face. Explosive diarrhea, vomiting, bleeding, severe itchiness...

But symptoms are not always as obvious. That doesn't mean that they are any less important.

As in Lilly's case, there was increase in fearfulness. But things like summertime increase in fears is normal for Lilly. Then there was some decrease in activity and stamina. Hiding behavior and change in elimination habits. Hair loss...

Beware of racionalizations

I think it is our tendency to nurture denial. Decrease in activity and stamina is easily attributed to weather, being tired from _______ (fill in your racionalization), or simple aging. “He just matured and slowed down.” There is no such thing in dogs, my friend! Dogs don't slow down because they matured, they slow down because being active had become difficult and/or accompanied by pain.

Even pain is sometimes considered normal in a senior dog!

When I joined hubby and our guys at the friend's farm recently, it was just couple days after Jasmine started favoring her front left leg again. I was upset about it and we had an appointment scheduled with her chiropractor.

The friend was complimenting on how great Jasmine was looking (and she was) and how well she was doing. I agreed but noted I was concerned about her front left leg.

“Well, she's eight years old,” the friend said.
Yes, she is, but she was eight ears old three days ago too and was pain free!

Just because a dog gets older it doesn't mean they won a frequent-flyer-pain-card!

Pain is not normal at any age! Pain is a symptom and needs to be addressed. Slowing down, not wanting to jump up on the couch, reluctance to play ... are not signs of maturity, they are symptoms of pain.

JD's buddy at the farm, Griffin, used to be his play buddy since JD was a pup. They'd play and play all day until they'd drop. Griffin is a Labradoodle and he is 6 years old now. He suddenly doesn't want to play with JD any more (which is breaking JD's heart).

What do you think? Had Griffin became too mature for silly play or should he be examined for signs of arthritis or other health problem?

The frog in boiling water

Gradual changes are the hardest to notice. Because they happen a little bit at the time they kind of became the new normal. Just like the frog placed in cold water that is slowly heated will not jump out. It doesn't work out so great for the frog!

Any signs that could be attributed to aging should be examined.

I think using what your dog was like when they were younger can serve as a good baseline. Symptoms of arthritis, Cushing's disease … are all too often contributed to aging.

Straight out denial

denial n. refusal to admit the truth or reality
Source: Merriam-Webster

Nobody wants bad things happen to their dog. Denial is really hoping that what you're seeing isn't what you fear it might be.

The first time Jasmine got up and was limping on her rear left leg, both hubby and I hoped her leg just fell asleep. Maybe her leg just fell asleep. Maybe she just laid wrong. Maybe she's just a little stiff. Hubby, eternal optimist, God bless his soul, is always trying to offer one of these explanations. But experience taught me otherwise.

Beware of “maybe it's just” explanations for what you're seeing

Maybe it's just heat was the first thought of Duncan's parents when he became lethargic and listless. Three days later he collapsed upon arrival to the emergency hospital and was diagnosed with Immune Mediated Hemolytic Anemia (IMHA).

Our neighbor's though it was just the heat when their dog collapsed. He died at the emergency hospital of heart failure.

Even just the heat can be deadly for your dog!

Know what is normal for your dog!

Know what is normal for your dog. Note and acknowledge any deviations from it. Noticing and addressing early symptoms can make a world of difference, and, in some cases, it can mean the difference between life and death.

Resist denial and racionalizations. The only way to deal with a problem is by facing it. And if by some chance you do end up in the veterinarian's office with a false alarm, trust me, it's the better alternative.

It's your dog's health,
Jana

Dog Development

This is another awesome iconographic that is brought to you by pet365. This one will help you understand dog development stages.

All dogs pass through various stages as they grow and develop. 

Psychologists use the term critical period to describe a specific time in a dog's life when certain experiences have a lasting effect on their psychological development.

Understanding these critical periods and dog's stages of development will better help you understand your dog's behavior and how to handle him during these special times.

Adoption Monday: Rocket, Greyhound, Middleburgh, NY

On Saturday Jasmine went to see her chiropractor. In the reception she met a male Greyhound who is getting physical therapy as part of his knee surgery post-op.

He was a racing dog who was tossed after he busted both of his cruciate ligaments. Yes, that's how they get treated.

Jasmine gets along with all dogs, but she fell in love with this guy. They were both quite taken by each other. It was love at first sight. His new forever parent had a hard time convincing him that it was time to go.

His sad story has a happy ending, he found a good home where he is treated like a member of the family and not like an expendable commodity.

Thousands of Greyhounds are not as lucky and are destroyed each year!

Meet Rocket, 4 years old, beautiful light brindle Greyhound.

He is neutered, had his teeth cleaned and is current on his shots. Heartworm negative.

Rocket will make an excellent family companion and will work well in an apartment or condo type dwelling.

Rocket was tested feline tolerant and is proving himself to be a very sweet boy with a nice mellow disposition.

Find Rocket's profile on Petfinder or visit Forever Home Greyhound Adoption's website.

Kidney Disease – Say What?

by Jennifer Coates, DVM

When I was writing my book the Dictionary of Veterinary Terms, Vet-Speak Deciphered for the Non-Veterinarian, the kidneys (not my kidneys thankfully, but kidneys in general) caused me no end of grief.  Not only are the kidneys themselves complicated, but so is the terminology associated with the diseases that affect them.

So here’s a primer on canine kidneys and all the associated verbiage. 

Kidneys: Where are They and What Do They Do?

The kidneys are two separate but essentially identical organs that are located between the abdominal space and the lower back.  Technically, they do not reside in the abdomen but within the retroperitoneal space (i.e., the space behind the peritoneum or lining of the abdomen).  The left kidney is usually a little farther back than the right.

Each kidney is made up of hundreds of thousands of nephrons, the functional unit of the kidney.  

Think of a nephron as basically being a microscopic filter attached to a long tube.

Image: Encyclopedia Britanica
The blood that enters the kidney progresses through progressively smaller vessels until it meets a single nephron.  There, “bad stuff” (e.g., toxins that are produced by the body’s metabolism) is filtered out and turned into urine, while “good stuff” (e.g., red blood cells and water) is either not filtered out in the first place or is reabsorbed before urine production is complete. 


Normal kidneys have many more nephrons than are needed on a day to day basis.  

Why is this important?  Because we can’t replace a nephron once it is no longer functional, and LOTS of things damage nephrons (more on this later).

But the kidneys do more than just filter out “bad stuff,” they also secrete a hormone that stimulates red blood cell production, play a role in regulating blood pressure, conserve water, help balance electrolyte levels, and more.

What is Kidney Disease/Failure/Insufficiency

A disease can be defined as anything that adversely affects the functioning of the body.  Therefore, kidney disease is anything that adversely affects kidney function… this could be infection, an immune disorder, degenerative disease, neoplasia (cancer), trauma, etc.

Saying that a dog has kidney disease is basically the same as saying that it has sick kidneys. 

What many people mean when they say “kidney disease” is kidney failure.  

Failure can be defined as a loss in the ability to perform normal functions to the point where the body experiences a significant adverse effect.  Some veterinarians don’t like the term “failure” (it sounds so untreatable) so they use “insufficiency” instead. 

A diagnosis of kidney failure usually means that laboratory values associated with kidney function (blood urea nitrogen (BUN), creatinine, urine specific gravity (USG), etc.) are found to be abnormal.

Another word that can apply to this situation is “azotemia.”  An azotemic dog has higher than normal levels of BUN and creatinine in its blood.

“Uremia” basically describes the same scenario but also implies that the patient feels poorly because of its azotemia. 

What all this means is that most of the kidneys’ nephrons are no longer functioning. 

In fact, the earliest sign of kidney failure seen in typical lab work is a low urine specific gravity, and this doesn’t occur until about two-thirds of the nephrons have been lost.  Azotemia doesn’t occur until at least three-quarters of the nephrons are gone. 

Acute or Chronic?

Kidney failure can be either acute (describing something that just happened) or chronic (describing something that developed over weeks, months, or even longer). 

Acute kidney failure is caused by things like infections, toxins such as antifreeze or grapes/raisins, and episodes of low blood pressure, but in some cases an underlying cause can’t be identified.  

If the incident kills off enough nephrons, the patient will die without a kidney transplant.  On the other hand, if the patient can be supported through the crisis, nephrons that essentially went “offline” but weren’t fatally damaged may recover allowing the body to return to a satisfactory level of functioning.

Chronic kidney failure comes on slowly and is a progressive disease. 

As I mentioned before, LOTS of things can damage nephrons.  Acute episodes may knock out a bunch all at one time, but the wear and tear of daily life also takes a toll and gradually reduces the kidneys’ reserve supply of nephrons.  Over time, the kidneys may reach the point where only one-third to one-quarter of nephrons are left, and the symptoms and laboratory evidence of kidney failure develop.

The International Renal Interest Society (IRIS) has come up with a staging system that lets veterinarians communicate how severe a dog or cat’s chronic kidney disease is.  IRIS uses the term “disease” because they include animals that are not currently in kidney failure but are at high risk for it in the future.

But this also begs the question, what’s up with the “R” in the “IRIS?” 

Here’s one more term for you.  “Renal” is the adjective form of “kidney.”  I guess “kidneyal” was just too much of a mouthful.

What Do Those Nutrients Do? Calcium

nutrient n. a substance required in the diet to maintain normal body function
Source: Dictionary of Veterinary Terms: Vet-speak Deciphered for the Non-veterinarian

The importance of calcium

We all know that calcium is an important component of bones and teeth. What you might not know is that calcium does much more than that!

IMG_4290
Calcium is not only found in bones, but it is also circulating in the blood.

The blood calcium is essential for a number of important functions, such as blood clotting, hormonal secretion, nerve conduction and muscle contraction (don't forget, the heart is a muscle too!).


Because of its importance, your dog's body has a control mechanism to keep blood calcium at proper  levels. When blood calcium levels drop, calcium is withdrawn from the bones to correct the deficit. If your dog doesn't get enough calcium in his diet, or cannot absorb it properly, it will result in loss of bone density.

There can be quite a substantial bone density loss before calcium deficiency might show up on blood work or present with other symptoms!

Because of her long unaddressed undiagnosed metabolic and digestive issues, when Jasmine was undergoing her first ACL surgery, her vet had to use a chuck and pin to drill through her tibial crest; he noted that he's never felt a softer tibia!

Other nutrients (such as vitamin D) and hormones (parathyroid hormone and calcitonin, a hormone secreted by special cells of the thyroid gland) play a regulatory role in calcium absorption, function and metabolism.

Kidneys are also involved in regulating calcium to phosphorus levels.

The dog's body takes the importance of proper calcium levels seriously.

With the bones serving as a repository, this system is to ensure that there is always the right amount of calcium in the bloodstream.

Image source: Visible Body
What happens when the fail-safe system fails?

Calcium deficient diet, or poor calcium absorption will foremostly reflect in the bones. Hypocalcemia, low levels of calcium in the blood, is typically caused by regulatory problems.

Hypocalcemia

Severe hypocalcemia can be life-threatening! Symptoms can range from muscle twitching or weakness to convulsions. Because the heart is a muscle also, hypocalcemia can lead to heartbeat abnormalities and even cardiac arrest.

Hypocalcemia is most commonly caused by disfunction of the parathyroid gland (often immune-mediated) but it can also be brought on by kidney disease, pancreatitis and other conditions.

The other side of the coin are calcium levels that are higher than normal, hypercalcemia.

Hypercalcemia

Hypercalcemia can be caused by a number of factors, such as cancer, Addison's disease or kidney failure. Overactive parathyroid gland or vitamin D toxicity are less common causes of hypercalcemia in dogs.

Hypercalcemia can lead to damage of any tissues but will most commonly affect the kidneys, nervous system and cardiovascular system.

Some of the symptoms of hypercalcemia include increased thirst and urination, lack of appetite and other difestive problems, lethargy, confusion and depression. In severe cases hypercalcemia can result in heart arrhythmia, seizures and even coma and death.

Got more respect for calcium yet?

The dog's body goes to great lenghts to keep the vital blood calcium at the right levels. It is not likely than poor nutrition would lead to hypocalcemia. Vitamin D toxicity can, however, cause dangerous and potentially fatal hypercalcemia.

What imballanced, calcium deficient diet will do, though, is have a damaging impact on your dog's bones and teeth. Calcium deficiency can be one of contributing factor in development of arthritis.

Disturbances in blood calcium levels require serious attention, diagnostics and treatment.

It's your dog's health,
Jana

Adoption Monday: Adopt-A-Less_Adoptable-Pet Week

Big black dogs. FIV+ cats. Senior pets. Special-needs animals. Many factors can make a pet seem "less adoptable." To promote these unusual (or, in some cases, too common) animals, Petfinder has designated Sept. 17-25, 2011, as "Adopt-A-Less-Adoptable-Pet Week."


Deep down we all want the perfect dog. But what does that really mean?

The perfect dog for you might be just among those nobody seems to want.

He might be a bit older. He might not see, hear or walk so well. He might not be all that good looking. But he might have a big heart and he might change your life in a way you never thought possible.

Shiloh is one of those dogs. A dog with a great disposition and no luck finding a home.

Breed: Hovawart Mix
Female
Date of birth: approx. Feb 2008
Location: Charlotte, NC

Frankly, I can't believe she is still hasn't found one. She is such a sweet and loving girl.

She suffered from severe hip dysplasia but had FHO surgery done on both hips and recovered well. Long term prognosis after successful FHO surgery is excellent. She might not be as mobile as other dogs but the source of pain and arthritis is no longer a concern.

All she needs now is a loving home and little bit of attention to her weight and exercise regime.

She's been waiting so long, she truly deserves to finally have a loving family of her own.

If you have any questions about Shiloh or the Hovawart breed, talk to my dear friend @Kenzo_HW or read related articles on his blog Kenzo the Hovawart.

Ready to adopt Shiloh?
