Still, in any case, these signs are worrisome because they just are not what we'd expect here.
Now in regards ***** ***** you can do, it does depend on what more subtle signs he is showing. If you think he is nauseous (ie lip licking, tender in his belly, gagging) or we just want to rule that out, then you could try him with antacid. Examples of those we use include :
*Pepcid (More Info/Dose @http://www.petplace.com/article/drug-library/library/over-the-counter/famotidine-pepcid)
*Zantac (More Info/Dose @http://www.petplace.com/article/drug-library/library/over-the-counter/ranitidine-hcl-zantac)
* Tagamet (More Info/Dose Here @http://www.petplace.com/article/drug-library/library/over-the-counter/cimetidine-hcl-tagamet)
Otherwise, we'd need to think about breaking this diet trial and seeing if he perks up on his normal food. We could see the allergy signs return, but if we can get him feeling better then we'll have determined what was triggering this.
