Meet Tucker! Tucker is a 5 year old Labrador Retriever who first came to Headon Forest Animal Hospital in 2012, presenting with itchy skin. He started to chew at his paws and lose his fur. As allergies are quite common in dogs, Tucker was sent home with some medications to help with the itching. Eventually, Tucker was transitioned onto a hypoallergenic diet and the combination of both food and medication has offered relief to his situation. In early 2014, Tucker came to us with a suspicious lump on his ear. In order to determine exactly what the lump was, Tucker had to have the lump aspirated with a small needle for cytology and sent to the lab where they would look at the cells under the microscope. The results came back a few days later and the outcome was that Tucker had a Mast Cell Tumor on his ear. Mast cell tumors are one of the most common skin tumors in dogs and if detected early can be removed with little chance of reoccurrence. Tucker was then sent to the Ontario Veterinary College to have the tumor removed. Because the tumor was found early, Tucker did not have to lose his ear and is cancer free. This is a great example of why early diagnostics are important and preventive health examinations are a benefit to pets and their owners.
