My poor dog inadvertently ran into a patch of grass that had a swarm of wasps! I ran in after seeing him dash about in circles and got him away. He was limping and so I brought him home and gave him an antihistamine as I wasn’t sure if he had been stung. He’s now behind the couch crying and came out and laid down and lifted his back leg. I examined foot and leg and couldn’t feel any lump from a sting. He went into the kitchen and began nibbling his back paw and so I soaked it in saline just to be on sage side. He has quite big testicles so I went to pad the testicles with the cotton pad and he jumped out of his skin (water isn’t cold!). Both times I’ve tried to check his balls he is very reactive so I don’t want to push it but what do you advise if he has taken a stinger to his jewels? They don’t look swollen and they don’t feel hot. Do I just leave it until morning and see how he is?
