I love dogs. I have two of them, and I love them to bits.
I think this could be a thoughtful handmade Christmas gift for the dog lover on your list. I even have one of these glass canisters sitting on a shelf in my kitchen, just waiting to find its true purpose in life.
You could also fill it with homemade, healthy dog treats. There are millions of recipes out there. I like this one because it also helps fight doggie halitosis.
