wow thanks guys for all the advise. I have taken bailey in for some blood work, and sadly she they found out her plat lets were low and she had limes. She just took her last pill for that and hopefully everything is back to working order. I will be asking my vet for a better flea med just to be sure that trifexis isnt what is causing this or contributing. my vet also said the to write down when she has them, how long, how many per month and we can go from there, basically what all you guys were stating. They are not grand by any means and I think i worry more then she does. The vet said pheno is to harsh for what she has right now so in case it happens again we have valium on hand to inject her with to help release.
