Warning Signs

Skin cancers rank the most common cancer in dogs, while bone, blood, gastrointestinal tract and lymph nodes are also sites where cancer cells develop. Cancer accounts for almost half of the deaths of dogs older than 10 years of age.

Watch out for these signs and behaviour changes which are indications that you should schedule a physical checkup at your vet’s office as soon as possible: an abnormal new lump, changes to an existing lump, sores that refuse to heal, discharge or bleeding from any opening (nose, mouth, urinary, etc), difficulty in passing motion, difficulty in breathing, vomiting and diarrhea, limping, foul breath, body odour, and loss of stamina. Remember that early detection increases your canine’s chances of survival.

Diet and Cancer

Amongst other factors, poor diet and nutrition based on processed foods are largely blamed for our modern day health problems faced by humans. Similarly this is what our furry pets are facing too – they rarely eat raw and are eating heavily processed dry foods. A change in diet especially during the time when they are suffering from cancer plays a key role in helping the animal fight cancer.
