My mixed breed dog (Golden Retriever/Lab/etc. mix) is almost 17-years-old & suffering from a definite neurological condition. We just haven't been able to get a diagnosis or any definitive answers (or, in some cases, any answer at all) as to what could be causing all of the different symptoms he is experiencing. I should start by saying that he has been unable to walk on his own for quite some time now & requires the assistance of 2 people to help walk him around, which we do quite frequently throughout the entire day (as well as overnight). It is not just because he has lost strength in all of his limbs, but because he has a tendency to want to curl his front paws under & to cross his back. Sometimes these issues are more pronounced than other times. Sometimes his walking is actually quite "good", while other times it is a huge struggle. There seems to be no reason for the change from one state to the other. What is most unusual is not just his propensity to want to walk in only one direction, but that this direction CHANGES. Sometimes he favors the right & it is impossible to get him to turn to the left; other times it is just the opposite (favors the left, can't get him to turn right). The change always occurs after he has had a long sleep. However, he can have a long sleep & wake up wanting only to go to the left, and have another long sleep & still wake up only wanting to go to the left. And then perhaps the next time when he wakes up from a long sleep, he only wants to go to the right, & it could continue this way (right) for a couple of days straight. Again, there seems to be no particular reason for this change in direction either. Nothing different about his sleeping habits. He ALWAYS sleeps on his right side, & in the same position, which is "upright", not completely on his side. (He will NOT lay on his left; if we place him on his left, he has an absolute fit about it. He, however, has never really been much for laying on his left, even before his problems began). I should comment that he is, understandably, very frustrated with his condition. He likes to do things on his own, to be up & doing when he wants, so being confined to his beds leads to a lot of crying. As much as we do get him up & walk him around, sometimes he is simply insistent on staying up (we cannot fulfill that desire constantly!) & so he will cry almost non-stop about his situation until he wears himself out, if we do not get him up. He does not wear himself out easily (we do not know how he has the energy), but sometimes we simply cannot get him up over & over again. Of special note is that, along with this, we have noticed a definite correlation in the type of distress he displays at these times, with the direction he is wanting to move in at the time. If he is wanting to walk to the left, his crying is "calm" (even though constant). If he is wanting to walk to the right, he squirms & flails something awful, tearing up the training pads we put on his beds & crying wildly. He is extremely difficult to calm in these times. The only way of doing so is getting him up. All of our local veterinarians whom we have spoken with have never heard of a dog who has a tendency to want to walk in one direction experiencing a change in this direction. They say that if a dog favors one direction, it is always that direction. Do you have any idea what could be causing that symptom especially, & also all of the others our dog is experiencing? It is a huge mystery to us, is very distressing, we want so badly to help him, & to at least have better, more helpful answers. He has had blood work done in the past month, CBC which was almost perfect, & red and white blood cell test was also very good, nothing of concern. Back x-ray showed no major problems. He did not have a neck x-ray which we wanted him to have (apparently it is not easy to do), as we feel that is at least where some of his problems lie. He hangs his head way underneath him when walking. Other symptoms of note are mouth-smacking at times, as well as a head & shoulder jerk at times. Also, drinking water when standing up is difficult for him, but when he is wanting to walk only to the left, he gets much better drinks of water. It is near impossible to help him get a good drink while standing up when he is favoring the right side. Left side, in all regards, ***** ***** a much better condition for him to be in. We dread him waking up wanting to go right. His appetite is for the most part pretty good, by the way. In his younger years & before any of these problems started, his demeanor was always extremely calm & laid-back and extremely gentle & well-behaved, wanting only to please us in everything. He is another member of the family, very dearly loved, & we would do absolutely anything for him. My apologies for writing so much, but I wanted to give every bit of information I could think of. Any help you could provide is greatly appreciated. Thank you.
