you hate to diagnose just by a sentence so I will not attempt to do so. But this did happen to Cash when he was a year old. but it was after a week of fever, no fever, fever and then he went lame at which point we were rushed to a neurologist. It was never 100% diagnosed, but he responded to two antibiotics so it was likely tick borne or a protazoan.
sending out good wishes to your sister and her baby. it's a good thing they are at the vet and if the vet doesn't suggest a neurologist or just treating for tick borne diseases. please keep us posted.
I am relieved Chloe seems to have made a full recovery. She is not on pain meds anymore. However she does do a quick yelp if my sister picks her up in a certain way. The vets did palpate her abdomen and back and she didn't yelp at all then.
I think we were all extra worried because just a year ago their lab, who was 10 plus years, had the same symptoms of not using his back legs and he quickly went down hill and died. So we were all frantic that it might happen again.
Thanks for your support. My sister always says, "How do you know so much about dogs?" and my response is I have read a lot of Threads and Posts on the Havanese Forum!
A couple of days after we brought Gidget home she just stopped moving, except to curl up in a little ball and start shaking. Took her to the vet who took x-rays, etc. but could find nothing wrong with her. She believed and we agreed that Gidget had just been playing too hard and had strained her back end. We've since learned that Gidget doesn't have a very high tolerance for pain and maybe tends to exaggerate a bit, especially when one of the cats takes a swipe at her!
