You can do a magnetic lock, but that can be kind of a PITA.

 

I have a few friends that have a Great Dane who likes to get into cupboards they tie them closed, but that could be a pain. If it is just one double door cupboard what about a small metal slider lock just screws in, might look the greatest but would do the job.

 

I've tried everything and still can't foil my Siamese cat.

 

What about the plastic locks that are inside the cabinet? Again, not convenient to open easily but can't be chewed off.

I thought that's what he was talking about, is there another plastic kind? There's just enough room with the cabinet partially open like in the picture that a really determined dog could probably stick their nose in and chew at the plastic, but if the OP was referring to some other kind of plastic lock, the one you posted would probably be the best and easiest solution.

How is he opening them? If he is pulling on the nob/handle just remove it. Have you caught him in the act?

 

Actually my cabinets do not even have handles or knobs, or any closing mechanism. He (or they) are somehow pulling at it (guessing) and getting a paw or nose in then opening it. I've never caught them, but I've come home to find it opened and stuff within eaten .. yesterday it was some uncooked rice, and some old protein powder stuff. Today I've put screws and wrapped wires to keep them out, but I want to do something better looking that is easier to put on and remove.

Kiya -- those look very interesting, are they metal, and where did you find them? Thanks.

 

I had these for 8 years and never had a problem. Used them for all 3 dogs none of my dogs ever showed an intrest in getting in the cabinets.

 

Store citronella candles in the lowers?

 

I probably got them in walmart, I got the picture from amazon they have a lot of different types, mine are plastic

We have the magnetic Tot Loks and they are AWESOME. You cannot see the lock from the outside, and you use a magnet held against the door to unlock it. We had them to keep kids out and they work great. No dog is going to get that open
