Hello - I"ve posted here about Nico's allergies and I suspect that this occurs because of the allergies but I wanted to ask you all what it might mean when I pet him on his back and sides and belly, he almost recoils in twitches and the leg moving in the air - you can pretty much tell he prefers not to be touched. I can stroke behind his ears, his muzzle, head, etc. What the heck is going on? Are his allergies causing him to be so sensitive or could it be something else? Is he just ticklish? I want to pet and stroke my dog! Thank you!
