There is another post about flees/ ticks on biospot efficiency.. I didn't know if you have seen it.
Here was my response to that inquiry. They get so bad here in the spring and the summer, both dogs have the lyme vaccine. In addition to the K9, I do use another natural product that seems to help here. The natural stuff needs sprayed over them daily... if needed more. I try to make it part of my morning ritual when they go out to pee.
Response to Biospot post:
I have never tried the biospot.. but this is what I have tried... don't know if it will help at all.
Here is PA we have several problems with ticks, especially since we live in the woods. Frontline did not work on Sadie Mae. Per my vet, we went to K9 Advantix. It seemed to work better but did not totally reslove the problem. On real bad months, we combine it with the below.
So I don't expose her to any more chemicals and pesticides than I have to, on the "colder seasons" when it is not as bad, I goto Flea Flee. It is an all natural essential oil blend to help protect against fleas, ticks, and other insects. It also helps to give her that "shiny look". A little goes a long way. For the dogs it is 1t. Flea Fee, 2t Dawn detergent, mixed w 1 pint of water. Place in a spray bottle... shake up.. and spray. I purchased it at the the Blue and Grey Cluster Dog Show. It is made by Nature's Pharmacy. You can even use this on the family if you do not add the soap.
The Chow Chow has severe allergies. We actually had to goto a tick collar, preventick D for her. She was trying to rip her hair out with the topicals. Due to the thickness in hair, ticks are not as much of a problem on her. She still would get an a few on her ears, so I would cover her eyes and spray the natural stuff on her chest and around her ears. It seemed to help.
The bad thing is .. with the flea flee, you do have to apply it often.
