As your dog or cat gets older, there is a 50% chance that they will develop cancer. However, if you catch it early, it can often be controlled or even cured.
The signs to look for are:
Sores that will not heal
Swelling of a body part
Weakness or soreness in a limb
Change in bowel habits
Unexplained discharge or bleeding
Poor coat quality
Pale skin, gums, tongue
If you see any of these symptoms take your pet to the veterinarian for a checkup. The key to noticing these symptoms is to give your dog a daily quick once over, and a careful once over every week.
This can be coupled with a weekly grooming session. It can be more difficult to spot some of the symptoms of cancer in pets that have long or dense coats. If you run your hands over your pets entire body on a weekly basis, you will be able to feel many changes in their skin, limbs and coat. It only takes a few minutes and most pets love the attention.
