My sach keeps scratching everywhere in the house. There are fur and a little black like pepper spots that keep falling from his skin. I took him to the vet and, after an examination, came to know that it was dog fleas. He prescribed an injection, and we have been treating him the same for a while now, and there seems to be not much of a difference. We decided to look for an alternative solution online and came across a website that offered some flea tablets and sprays. Has anyone bought such dog flea medicines for their pet? Could someone help and advise me on this?
