I have 4 dogs and i live in the woods on a big property. Our dogs always get fleas and we get rid of them but it doesn’t always work as planned. The house wont have fleas for about a month then they all come back because our dogs play outside most of the day. Now the fleas are worse this time of year and one of our dogs has them worse then the others. Shes constantly itching and scratching, I don’t think she does anything else, but that. I’m really worried because she is tearing at her skin so bad her hair is falling out on her tummy, she just grew all her hair back from last time, she is a beautiful golden retriever about 8 years old in November, in good shape, but the fleas. As You can see we have spent a ton of money getting bombs and flea shampoo and flea stuff to go on after, but it doesn’t work that long and the fleas keep coming back, what should i do to get them gone for good?
