Why Does My Male Chihuahua, Drag His Bottom On The Ground. Are There Glands That I Can Empty For Him Or Is This How They Empty Those. Or Am I Way Off?
I think you are right it would be his glands that need to be emptied.
Chances are that he is trying to empty his glands. My male has problems with emptying his, so we have them expressed by the groomer. Before we knew he had a problem expressing them, one burst. It was very painful for him and very messy.
