Again, same here. I think my dogs pick up the fleas from our walks. We have a few strays.. Or what I THINK are strays.. they look kinda healthy as if they get meals enough, but not too clean
Also I just moved into this house 3 months ago.. so everything is still very new and shiny and clean. So I don't think the fleas comes from anywhere in my house. We have stray cats too, always comes into our yard to poop. I think it's because we have lotus plants, and there's clean water in the pot. I have no heart to shoo most if I see any. One was pregnant
I do know the neighbor's dogs opposite across the street has fleas
2 golden retrievers, 1 german shep, and 1 black lab. I see the dog's caretaker picking fleas from their bodies all the time. Yes I snoop from the balcony to look at them in their front yard. No I don't feel guilty
it's for the good of my dogs too.
Sigh... I don't know what to do if my dogs cannot take walks.. They have begun to love it. But i live in a tropical 3rd world country
