I have an 11 year old Pom named Moose. He begin showing signs of a collapsing trachea, the vet gave him Tusogen (hydrocodone) once he begin this loud, harsh intense coughing.a month ago. Then sent us to a specialist who....hasn't really done anything except want to give an inhaler OR 'scope him" then prescribe an inhaler. Meanwhile outta the blue one morning 5 days ago, he could barley walk. (This is the issue, only mentioning the trachea/cough jus in case its related). When he tries to walk, he goes into a circle and flops down. His right rear leg is what looks like "stuck inward", like shifted to under his center, or he's doing that. So back to the vet where they said it could be a brain tumor is always possible, but unlikely, she thinks its a disk problem, Except, his Front right leg has issue too. This leg its like he can't or won't move his wrist to set the paw down. Now he is on Tusegen, Gabapention (like a nerve pain killer?) and Metacam (anti-inflammatory) . I almost think he had a stroke, except sometimes, even first thing in morning, he may trot along and you can barely tell there's an issue. Then that afternoon, he tries to stand and just can't do it. His appetite sure is unchanged, and you can read his feelings on face easily he's happy for most part; So I don't know whats the problem, stroke, tumor, disk, hip displacement (vet didn't think so) Anyone have any ideas on this or seen / heard of this ?
