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.
Best Answer: The best age is between 4-6 months, so you spay BEFORE your dog ever goes into heat (but after your pet has had all necessary vaccines). Spaying before the first heat cycle decreases the chance of later developing mammary tumors (breast cancer) by 97%.After the first heat the chance is decreased to around 80-85%, and after the 4th heat there is almost no decrease.deally she should be spayed between 4-6 months, BEFORE her first heat cycle. This will help reduce the chance of breast cancer later in life. Also the spay surgery once they have had one heat will be more involved.
