If your petâs brain or spinal cord isnât signaling correctly to the bladder, this miscommunication can cause urine dribbling. Damage to the pudendal nerve. This is a problem of the lower back in dogs â I see it often in my practice in older dogs with arthritis, degenerative joint disease or trauma to the lower back.
Hi there, There are a number of things that could be going on - but laboured breathing really worries me! Any time an animals has difficulty breathing, he should be seen by a veterinarian immediately! The wobbliness could well be because he is not getting enough oxygen to his tissues. A common reason for laboured breathing is congestive heart failure. In an older dog, this could be caused by a few different things, but mitral valve disease would be the most common. Basically, when the heart beats, not all of the blood inside it is pushed forward as the mitral valve often becomes leaky in older small breed dogs.
