Thank you for your input I appreciate it!With that much bump-ish. That strikes me as more of a food allergy or maybe something in the yard??? Or I suppose he could have an allergic reaction to mosquito's???
But, insect bite's tend to result in localized swelling?? I think you need to get him to a vet to get a better idea of what's going home ...but changing his food could not hurt either.
Keep us posted.
