my 8 month pup has been having skin problems. first it seemed like bug bites, than allergies. he was on benerdryl,comfortis, itch stop, panalog and now the vet is giving him virbac genesis. after reading this label, i am trying to make sure it's okay to give him. he will be licking this area i'm sure, and i was just wondering if you have had used this product and is it safe if my dog should lick it. it also says to use in a well ventilated area and to wear a mask. sounds scary to me. have you used this product? what's your input on it? thanks for your answers.
