Roundworm, ringworm? Wtf.?

Well there isn't an alternative... This can cause mange (where your dog has hair loss in multiple spots on his body until it completely takes over). Unless of course you take him to the vet and get the medication. You will be spending more money if you wait than if you go now. I know this because my dog just recently had a similar problem. It can be easily taken care of if you go to your veterinarian. If it's in your dogs head it seems like it could be even worse but Im not sure... Like I said go to the vet!
