The signs to look for are:

Abnormal masses
Sores that will not heal
Swelling of a body part
Behavior changes
Lethargic behavior
Weakness or soreness in a limb
Exercise intolerance
Chronic sneezing
Difficulty breathing
Difficulty swallowing
Weight loss
Change in bowel habits
Excessive urination
Unexplained discharge or bleeding
Abnormal odor
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.
