My 5 month old border collie is totally obsessed with bubbles. She loves them, they're her favourite game. When I take her to the park I play bubbles with her, and she gets a really, really good workout as she runs all over the park and jumps up at them to pop them. She could do this for ever....i get bored before she does, usually after about 45 minutes or when the bubbles run out, so with all the running and jumping it's like an adult going to an intense aerobics class or a good swim/football game.
I just use the kids ones you get in The Works or pound shops, sometimes with a cheap bubble machine. I know there are ones marketed to dogs, but I figure if they're marketed for children, they must be safe for dogs.
Does anyone else's dogs like them?
