This is a query for my DGDog. He's a large beautiful Nova Scotian Duck Tolling Retriever (Toller for short) with a thick long coat and a sensitive skin. And he has fleas. Again. He's treated regularly and the house has been sprayed several times with various brands of flea killing potions but within a few days he has the little blighters again. Any suggestions or advise on what brands work would be really appreciated as he regularly comes to stay - and brings his little friends with him.
Do you agree with me or parent and child?
