I am not sure about it, but I think my dog has got pollen allergies. Usually we walk him through our neighborhood only and no issues occur. Occasionally we send him with dog walking service people when we are busy with something. At least two or three times after the walk, he was terribly irritated with something in his body. He was trying to scratch away something. We asked dog walker where did he walk the dog. He walks quite some distance but importantly he walks a fair distance around a community garden. So I guessed that might have caused something as I have already heard about dogs pollen allergy issues. So I asked the walker never to go near the garden with the dog. And with no surprise, dog never showed any issue after that. Even a vet after hearing this symptoms suggested it might be pollen allergy issue.
