Hello it's very worrying when there anal glands get infected and it makes the dog miserable, my Riley had to have his removed at the age of 7months as they were constantly infected and then he ended up collapsing in pain so we ended up having both removed, he was sore after the op and had a few little accidents regarding his number 2's but it was the best thing we did for him it's not affected his bowel movements and his feathers cover his two little scars he had the were very tiny anyway, I would say do it as sounds like your porr doggy is in pain and we had a few days of him feeling sorry for himself but he soon got over it and I wouldn't hesitate to have the op again if Bonny needed hers doing x x
