I have a young puppy that loves to pull up my carpet.
What he is doing is pulling up the carpet where it meets the tile floor in the entry way then chews on it and the pad,
The first time he did it I was able to cut out the part he chewed and re stretch the carpet, Well he did it again and I need to patch the carpet this time which I can do but I don't think I can stretch it any more.
My question is there anyway I can use a T molding to put down where the carpet meets the tile? I just don't know how I would get the T molding to stay in place and there isn't much room with the tack strip to even put the molding in.
I am thinking if I can cover the end of the carpet where it meets the tile the dog wouldn't be able to get a hold on the edge of the carpet and pull it up.
And don't tell me to do away with the dog, It's my wife's dog, And I am sure that would never happen. So I just need to get the dog to listen to me, She is just a puppy and I think that she will grow out of this chewing.

 

I moved this to Rugs, since your question is about rugs. I would never tell anyone to get rid of their dog.
Can't answer your carpet question, but they do stop chewing when they're a year old. Till then, they're teething, bored and full of energy, so they chew things. Either try tiring her out more or maybe you can crate her and fill it up with lots of chew toys, when no one is home.

 

Relocate the tack strip and the transition piece goes in next to the transition. Are you on a slab or wood subfloor? Get a lap type transition piece that sits both on top of the tile and on top of the carpet. The side profile would be fatter on one side (sits on carpet) and thin on the other (sits on tile).
