We tried this on my dog when he was a puppy and it didn't seem to work very well. He is 2 yrs. old and over the chewing phase but perhaps I'll video him to see how well he reacts to it now.

Pros: None

Cons: Didn't work

First of all, you have to be DESPERATE to spray a liquid on your furniture. There's a pretty big risk of it being ruined. I tried this on our first German Shepherd when she was a puppy. NO EFFECT. The taste didn't bother her at all. I guess when you're teething, you're DESPERATE to chew!

Pros: Might work for small dogs

Cons: Risk ruining your furniture; no effect against a chewing German Shepherd puppy

I have used this many times. I have only been successful maybe half the time. Some puppies and dogs get use to it and you have to use alot of it and it still may not keep them from chewing on furniture. It is best used for surgery so they do not pick on their stitches.

Pros: some dogs don't like it

Cons: some dogs don't mind it

I used this for my oldest dog when he was a puppy. He did not stop chewing, the only thing that it did was make him drink more water to get the taste out of his mouth.

Pros: None

Cons: Didn't work

When I had a puppy, this didn't deter him from chewing something if he was determined. A friend of mine swears by it. I guess it depends on the dog.

Pros: available

Cons: didn't work for me
