My 6 year old cavalier dog couldn't walk first thing this morning, having lost the use of his back legs, he then started walking but was very weak on his right hand side. I took him to the vets , his symptoms were a lot better by then, but still had a limp to his front leg. there was no pain or loss of mobility to his joints. I had been meaning to go to the vets as his eyes were sticky. This was found by the vet to be lack of tears to the eyes. Between his paws was also very sore and red. So he was given a anti-inflammatory injection and we have to go back in a weeks time. So now we are looking at possible dry eye syndrome and ??SM (Does scratch in the air, with high pitched scream, quite often). I just hope that they are proved not to be the case. Any thoughts would be appreciated.
