I'm pet sitting a Weimaraner, Josie. Ripley has been around her before as she's a 'relative'. She was at our house for several hours before I noticed she had a fair amount of fleas. I gave her a bath right away with TropiClean shampoo and tea tree oil. I don't have chemical flea stuff in my house. The washable items she touched are in the washer now. But what about the cardboard that was in her cage? It's now outside but do fleas attach to things like that? Who knows what's in the yard now. I keep feeling like I have creepy crawlies on me! What other steps should I take? I'm worried the fleas are still going to spread like wildfire.
