Our puppy keep chewing on plants and vines. She's destroying our yard. How do we break her of this?

Give her a chew toy. She could do harm to herself by chewing on a plant that will poison her.

Hello, I have the same problem, I have a 9 week old golden retriver pup who just loves tearing leaves of plants and biting flowers off! Very aggrivating!

It can be very hard to teach a dog to stay away from something that it is not allowed to touch when this something is outside, and you can't always be there to correct. But here's a way to teach her without being there. Its simple douse the plants in something she would find disgusting, on Google some of the examples include bitter apple or bitter lime. It also suggests a mixture of 1 part water and 3 parts tobasco sauce. But remember like
tickle said some plants can be toxic if this is the case don't take the chance, move the plants out of the dogs reach.

Put up a barricade until the pup gets older. They won't always do this, but the more you say NO, the more they will do what you don't want them to! And like Rex said, check on Google for some tips !
