I'm at a loss as to what I should do, my poor rough collie is miserable. He spends all his time scratching and chewing on himself he is now missing hair from scratching so much. He is crawling with fleas and covered in tiny red scabs from them biting him. I have been treating him religiously with front-line every month for 5 months in a row right on time with the correct weight. I've taken him to the vet and they told me I would see no improvement for at least three months of continuous treatment 3 months went by and I've seen no improvement. I called and asked if there was anything else I could do for my poor dog. They said the front-line had to be working and I was just seeing a flea here and there and that I didn't have an infestation going ( I do). I asked them if there was another flea product I could try that was safe for rough collies (Since many rough collies and a few other breeds cannot tolerate most flea meds do to the chemicals used in these preventatives, and many have died from this genetic trait). The vet tech on the phone told me she didn't know what else I could use because she had never heard of rough collies being sensitive to anything, and acted like I was making this bit of info up. She said flea dips only work the day you you dip them (couldn't tell me if they were safe) and told me I should call the front-line company and see if they would give me a voucher or coupon so I could buy some more (because it has been working great for me and my dog). All the other vets are to far away and won't sell me anything unless my dog has been there before, I can't drive and have no way to get him there to be seen. I've tried tons of herbal/natural treatments and nothing is working. I'd like to flea bomb the whole house, give my poor dog a flea dip (for fast relief) and then continue to treat him monthly with a flea preventive that won't kill him but actually works. If anyone knows a bomb product and a safe treatment for collies please tell me, my current vet could order it if I just tell them what I need.
