Scooby my 5 month old cavalier drools heaps when i walk him on the leash. He's absolutely fine at home and doesn't drool at all. But soon as i put the leash and collar on and walk him, he's drooling. Sometimes, he does tug on the leash a bit so i guess there's a bit of pressure on his trachea, but is drooling normal for a cav? Or is there something wrong?
