Brain Tumors. A diagnostic test, such as an MRI or CAT scan, can determine whether or not your dog has an abnormal growth on the brain. Brain tumors, especially those in the cerebrum, can be a common reason for seizures in older dogs, but they are rarely the cause of seizures in younger dogs. The highest incidence is found among the short-nosed breeds such as the Pug, Boxer, Bulldog, and Boston Terrier. Tick-induced Diseases.
When to Spay. If your lab puppy is at least 6 months old, the time is right for spaying. Some vets, humane societies and breeders recommend spaying as early as 2 to 4 months, but the traditional age is 6 months. A lab puppyâs first heat typically occurs between 7 and 12 months so you likely want to spay before then.
The best time is at 5 to 7 months of age before the female cat goes into heat for the first time. Sometimes vets do it as early as 7 weeks of age. The vet authors of the above mentioned book say that early spaying does not cause health problems or long term behavioral effects. Hope this helps.
