ATTENTION ALL DOG VETS! HELP!!! my dog is losing lots of hair on his back!!?

uming the shampoo is new, your dog might have an allergic reaction to something in the shampoo. I'm not a vet, but i know something about dogs. I suggest you throw the shampoo away and get some conditioning shampoo or just plain old conditioner (make sure its for dogs) You might want to check his skin and make sure its normal looking if it isnt that proof to your dad that he needs de vet! o yeah and the fragrence in itz might have irritaded his skin or you might not have rinsed him well enough try rinsing him again and try adding some conditioner.... hope diz will help!
