Pomeranian spinning and barking

Hi all, I have a Pomeranian and its tail is infested with yeast which we have already bring it to see a vet. However, what was more worrying is that my dog was always barking and spinning every single day. I cant upload the video here for some reason. The vet couldn’t diagnose what is wrong and the blood result came back fine. Can anyone please advise me please I’m at my wits end.

ANSWER TWO:   Hello again - I am going to update this answer as my previous one may be wrong.  When you mentioned circling, my mind went to neurological conditions which may still be the case and should be ruled out (as I haven't seen your dog), in particular with regards to epilepsy.  However, it appears that there is a breed-specific tendency to circle in the pomeranian of which I was not previously aware (they have been quite a rare breed in the UK) to the extent that some people regard such circling as normal.  If, for example, you were to do a Google search you will find this behaviour entirely normalised.   In my opinion, even though this is common, may not mean that it is normal, about which I will do more research before passing judgement.  Thankyou for keeping me on my toes; your vet may have more information for you and I will see what I can find out (vet of well over a decade of experience!)

Hello!  I did some research and it was fascinating.  A simple Google- or Bing-search brings up multiple articles claiming that poms do this 'sweet' habit and that it is absolutely normal for them, because they are a pom.  However, what's interesting, is that these pages tended to be commercial blogs with links to the dog-breeding industry, the pom-breeding industry in particular - and nowhere was normal repeated circling for poms alluded to in the Veterinary Times, various neurological help pages or the websites I found written for vet students.  There, circling is described either as a pathology (disease) or at best, a negative  habit.  So I asked my contacts veterinary-only social media.

*on* veterinary - only social media

One of the most frequent comments is that vets are indeed witnessing this in pomeranians but by no means all of them; that it seems to happen particularly excessively when dogs are emotional, either positively (excited) or negatively (bored).  A few vets have tried to 'work up' these cases (find evidence for a cause), looking for things like shunts and knee pain, but found nothing. Some suggest that it could be a manifestation of epilepsy; your vet could speak to a neurologist for you, in order to get their thoughts on whether trying epilepsy drugs might be useful.  Another strong line of thinking is that it may be behavioural in some dogs, as a consequence of being caged / bored (a so-called 'stereotypy' like box-weaving in horses).  Others cite 'inbreeding' (ie it is coded for in modern poms' genetics, which may explain breeders' opinion that it is cute and normal - perhaps people have been selecting for it in poms by breeding from affected dogs).   Personally, I think that asking your vet to check the latest knowledge with a neurologist would be a good way forward.   However, I do not think that it is 'normal' for poms, simply common in them and 'accepted as normal for poms' by the breeding industry.  I do hope that something there helps.
