I'm hoping someone has some information for me. I know this is a nasty topic, but....anal leakage. I have 3 dogs - Lab mix, Jack Russell/Beagle mix, and Jack Russell. The Jack Russell and Russell mix have anal leakage problems. The Lab never has had the problem. The two dogs with the problem occasionally let forth with the nastiest "fish oil" smell ever. Definitely coming from the butt, not other parts. (One's a neutered male and the other's a spayed female.) They both eat different food - one Purina and one Iams. The Lab (without the problem) eats Pedigree. It's obviously not the food. They have a clean bill of health from the vet. I've heard that this problem can be linked to needing the anal glands "expressed." My dogs do not present any of the other symptoms, though, besides the smelly discharge occasionally - no dragging the rump on the floor, excessive licking, nothing. Any input? Help with my smelling problem please!
