Ok, I just looked at the stuff. It's k-9 advantix. Supposed to apply directly to skin once a month and interceptor for heart worm (monthly pill that she swallows). Hubby said he thought he got it on well enough, but her hair was pretty oily. Those BOTH came from the vet, were suggested by the vet. The vet has applied them to our dog before. Now, she was going in for more frequent bathing due to the itchiness. I thought it was similar to dry skin asked the groomer at the vet to take a look when we boarded her, she did and did not say anything was wrong, so I thought it was dry skin, it happens. Fast forward to last Thursday, almost 2 weeks after groomer at vet, she was really itchy and red skinned on her tummy. I saw some seed ticks, picked them off, took her to petsmart and said she had a dry itchy tummy, could you please check and do the wash that soothes dry skin. When I picked her up, they said everything was fine. Her little report card even said so. Fast forward to today, really itchy and moving up to chest. I now worry she may be allergic to something, so I take her to the vet. Vet says she has fleas, obviously not horrible since I can't see them when I rub her tummy, but fleas none the less. Since she isn't used to being so itchy, she really rubbed and rubbed and rubbed, hence the dry itchy looking spots. At our previous vet, we just gave her a pill monthly that covered everything and never had a problem, other than it was expensive. She is groomed monthly since she's a westie and needs haircuts frequently to be comfortable. I am pretty sure we caught it early, otherwise someone that was grooming her would have said something surely. After reading about the stuff and how it needs to be applied, I am sure it's operator error...lol.
