My one pup was scooting which i never understood because they have been dewormed twice already. So we clipped the hair i could see he was tender. I took him straight to the vet who said it wasnt bad at all and he did the dirty deed and gave him a shot of something to clear it up and he was fine the next day, the infection hasnt come back at all. But he said it can be from the change in diet from milk to solids, fleas, worms, faeces trapped internally or externally or even a stool which is too loose.
Apparently a dog naturally expels the glands when going to the loo, but if their stool is too soft it doesn't happen properly. They use these galnds to mark territory as well.
The vet showed me how to do it but said always remember to keep your mouth closed! ha ha! i said in that case i will bring them in if need ever be!
Like i mentioned, Taylor and Trigger never experienced this before so i never really knew the signs. The vet said it stings and is tender if not seen to properly and if it is left untreated and reaches an advanced stage or the abscess bursts it can cause infection and sometimes anti biotics or worse yet operating is needed.
So we learn! Gross but good to know i think!
