Throw me a Rope

AP here: I have now been dealing with Tonkas gradual decline for almost 2 months with no answers. The poor boy has been poked, shaved, prodded, physically manipulated, lasered and scanned with no definitive answers. Through it all he has been such a good sport and a gentleman and I have no doubt that he will keep on being such a "very good boy". It all seems so unfair since he is such a good boy. He will be 4 soon and he has never growled nor even snarled a lip towards anyone or anything. It is very frustrating that we have no answers and equally as frustrating that it is only about a 1/4 of an inch lift that the foot/leg needs to do in order to not drag or scuff.

We have had good days and then really bad days on good days he sort of lifts the foot with little drag
and on bad he drags and knuckles under. His bad days seem to come after medical consultations with
lots of pushing and prodding. Acupuncture seems to be the only thing that has not caused a bad day yet. I have noticed that lately when he stands at the food bowl his back end starts to sag and his legs bend. When he goes to lay down he starts down and then falls all the way back and then slides his front legs down with his left leg way out to the side in a straight position with very little bend
at the knee.

It is very frustrating that this does not seem to have a cause, or fit any particular known problem. If nothing can be done and this is how he is going to stay that is fine but I would like to know what the problem is. I don’t let him do too much because I don’t want to hurt him in any way but if this is it then I would like to get him back into a normal pattern (a new normal of sorts). I will take him to the park and let him see his friends and we will create a schedule for the urinary problem. I just want to him to keep him safe and happy.
