Acromegaly (hypersomatotropism) is an endocrine disorder characterized by progestin-induced hypersecretion of growth hormone (GH) by mammary hyperplasia, with resultant overgrowth of the soft tissue, bone, and viscera. In humans and cats, acromegaly is commonly caused by pituitary adenomas producing GH. Rare cases of pituitary adenomas resulting in acromegaly have been reported in dogs, but acromegaly is usually caused by GH production at hyperplastic mammary glands or mammary adenocarcinoma.
These pro-early neuter studies were not carried out long enough to evaluate the risk of cancer. In my experience, dogs neutered under 6 months develop less obesity and donât establish some of the âmaleâ behaviors that neutering is meant to treat. They are also less likely to jump a fence, fight, or get hit by a car.
Whatâs The Best Age? Adult dogs can be neutered at any age, but the best time is before sexual maturity. For many years, the recommended spay/neuter age was six to nine months. When a puppyâs future involves performance competition, ask your veterinarian and breeder about timing.
