POLYCYSTIC OVARIES. At left is a picture of grossly enlarged and cystic ovaries. They
measured approx. 2 x 4 inches in this dog and should have been approx. 1 x 1 inch or smaller.
Cystic ovaries can be painful and cause strange or absent heat cycles. In addition, they
can rupture and bleed resulting in abdominal pain and infection in some instances.
This dog had bilateral (both sides) polycystic ovaries. She had a painful abdomen, lack
of appetite, and weight loss.
This was something I copied off of this website for you:
Consequences of Not Spaying and Neutering.
Sorry that was all I could find about dogs though.
