My terrier is scratching herself everywhere on her body, not constantly, but a lot; she eats well, is happy and otherwise healthy. Is she lacking nutrients? I have started her on Dinovite and Fish Oil... so far, nothing helps. I am confident that there are no flea problems.
Sorry to hear your little girl is itchy. Canine skin supplement such as Dinovite and Fish Oil can certainly help with the overall health of your pet’s skin. There may be an underlying issue that is causing the itching. Many ailments can manifest into itchy skin, including allergies, parasites (fleas as you mentioned), infection, inflammation, etc. Each ailment will be treated differently. I recommend you have her examined by your local veterinarian to isolate the root cause.
