My dachshund gets impacted anal glands and the sooner you have them taken care of the better. You don't want them to get infected. After years of this I discovered my dog is allergic to all meat proteins with the exception of fish. When she get some beef or chicken in a product like a treat or dental chew with meat proteins she has anal symptoms. I have to read the packaging very carefully to ensure there is no meat proteins. It's not always evident by the packaging. If your dog has a chronic issue check with your vet to see if they can be on a fish diet instead of a land animal protein diet like beef, lamb, chicken etc...
