Pet Cancer Warning Signs

Pets are susceptible to the same types of cancer that people get. Cancer can strike at any age, but it is usually a disease of middle-aged and older dogs and cats. And it is all too common: Cancer causes almost half the deaths of pets older than 10 years.

Here is a checklist of possible warning signs of some pet cancers:

If your pet exhibits any of these signs, call your vet.

1. Your pet has a lump or sore that won’t go away.

2. Your pet is eating but losing weight.

3. It is hard for your pet to chew or swallow.

4. There is a discharge or bleeding from any body opening.

5. Your pet has a bad smell.

6. Your pet tires easily and doesn’t want to exercise.

7. Your pet has quit eating for more than a day or two.

Sometimes the changes are so subtle, and explained away by thinking it's just normal aging. My cat had lung cancer, but was so stoic and hid it well for some time. I had to make the awful decision to humanely euthanize Zeke after three months and $1,000 worth of comfort treatments:(. I don't wish this on anyone, it's a terrible diagnosis.

watch them really washing on a particular spot. It's a shame how much vets charge. My old hound got a cystic pimple. A tad over a $1,000. The vet wanted to do a body scan, because the lymph bodes are slightly swollen-probably because the dog chewed on the pimple and infected it. I told them-- No. I'm willing to let all of the surgery antibiotics work, and see if the lymph glands go down.

If your companion animal suddenly changes it's behaviour or appearance in any way, after two days take it to the vet. If it's a dramatic change then leave it only overnight before seeking professional help. The charge for a check-up by the vet is well worth it for your peace of mind, & many things are treatable if caught early enough.

My kitty Jessica who is 13 years old has cancer. Right now she is doing well on her medications. I hope someday there will be no more cancer that our furry family can get or humans for that matter. Cancer has been with us for centuries and you'd think by now there would be a cure or a vaccine to prevent it from happening. I'm supporting cancer research so that one day it will be a thing of the past.
