Gave this to Spike Thursday night, spent all day Friday at the vet. He is home now but still itching all over, scratching himself raw and walking like he has some muscular problems. Psychologically he is not right either. He is normally such an active dog but he has been moping around and really listless for the last two days. He whines everytime we leave the room and cries all night long. i know the itching will stop but I am wondering if anyone has experienced the psychological breakdown I have and how long that will last?? Thanks!!
