I have a 14 week old GS pup and a week ago I noticed a greenish/yellowish discharge from her girl parts. A few days later it got way worse (larger amounts of discharge). I took her to the vet and while at the vet her discharge was literally dripping down my pants (sorry for being graphic) and the vet said that it is clearly not normal and thought it was a uterine infection. Because she is eating, drinking, playing, etc like normal, he wanted to try and treat it with antibiotics to see if that helps, but he said an emergency spay may be necessary. We are not planning on breeding so spaying her is not a problem. Tonight, her discharge was a pinkish color. She is on day 3 of antibiotics and they gave her a shot of antibiotics at the vet as well. Is the change in the color of the discharge reason to take her to the emergency vet? And has this happened to anyone else?? I feel she is way too young to have these types of problems. Thank you for any advice.
