Bella had to go back to the vet today to get her needed boosters and when we got took her lastweek for her vet check she had ear mites so they wanted to check her ears too-anyway- I noticed that yesterday and today 2 different times she drug her hiney on the floor, she tested negative for worms lastweek but I mentioned it to the vet today and when she looked Bella had an anal gland that had (I am guessing feces) in it. It was so GROSS!!! The vet said they can get clogged glands and they would show me how to clean them....I said that was OK I will take her in when I notice a hiney drag

Is this something that happens in small dogs often?
