When you have that many animals you must treat all of them and you must make sure the fleas are not in your house. The fact is that one flea can make 2,000 eggs so if there is a flea on your dog they are everywhere. If your dog keeps having fleas that means you stiill have them in your house and they do get on the other animals. As a groomer I can tell you that they are very hard to see on cats. If your animals are going in and out it is very hard to rid your house of fleas.
You might try the comfortis on all your pets and have an extrminator treat your house and yard.
Good luck, it is very hard and veryn expensive to get rid of an infestation. |
