Hello everyone, I'm a newbie to this forum and I would really appreciate any advise that you may have regarding this problem that we are having with our little one. We have had Heidi for 3 weeks now, she is smart, happy, playful, eats & drinks well, her weight (3 lbs 7.5 oz) which we think is good for 11 weeks old and everything in the potty department is working well. Heidi seemed very healthy until a week ago when she had her 2nd set of shots. I'm not positive that being vaccinated is the cause but it seems odd that we never noticed anything wrong with her prior to the Injection, HeartGuard, Advantage & Kennel Cough. But since Heidi received all the above last week she is encountering these episodes about 8-10 times during the day. We have not noticed any signs while she is sleeping. I have taken two videos of her episodes (it won't let me attach them to this post) where she seems to go to another place, vibrates briefly (only a few seconds), her head goes up & back and then everything is back to normal. I took her back to the vet last Thursday to have her checked out, and the vet was lucky enough to be watching her when I asked her to sit and was about to give her a treat for being so smart when she had one of her episodes in front of him. The vet has not seen anything like this and he said that he has never heard of anything like this happening to a Yorkie after vaccinating, the vet gave me 4 doses of vanectyl-p to see if it will help. To date Heidi has taken 3 doses and her episodes have continued, and she now is congested, sneezing and this morning when she woke up she had a bout of which sounded like she was having trouble breathing, this to passed quickly, she does have a little bit of a runny nose. The vets office said they will call Monday morning to follow up with me. Has anyone else encountered this with their little ones and if so what is it and what should I be doing? HELP!!!!! I hate seeing my precious little girl going through this
