I was just going to post this same topic! Lola had her surgery on March 20th. She does the same thing. Yelps, then suddenly runs into the other room. That's how it started, but now she typically doesn't add the 'yelp' part. I've noticed that sometimes she will look back at the cushion or wherever she had been lying. Makes me wonder if she thinks something bit her. She will do it when she's standing too. This started happening about three weeks after surgery. For a few days she was put on Tramadol by the surgeon and that did not help. A few days later at her vet checkup, her oncologist put her on Gabapentin and it has really slowed the number of these episodes down. I wasn't fishing for the term 'phantom pain ' when I brought it up and she didn't mention it. So, when I did ask her if that could be the issue she said that there's no way to ask Lola what she's experiencing and I was glad she didn't commit to that terminology. However, I certainly think that could be what's going on and am glad the med is helping. 

Additionally, I read the link about Gabapentin. It says not to use the human form of gab bc it contains Xylitol. But I believe that is referring to the liquid form only. Is that right? Lola takes capsules for humans.

I just called my pharmacist and he said that the Gab capsules that I have contain Mannitol instead of Xylitol. It is also a sweetener which is so unnecessary for a capsule. I'm not sure what this all means for Lola as described in this link about it.  Mannitol

I'm concerned bc dalmatians can be prone to kidney/bladder stones. If anyone wants to discuss with your pharmacist, they will want to know the dosage and manufacturer. Mine simply said a special compounding pharmacist would have to formulate the gab without the added ingredients. I bet that's expensive!
