Why do dogs dig...

and bury their bones?

 

I had read before that dog digs because they are bored.
In terms of burying bones, maybe they do it to make sure their bones are safe and they are reserved. Lol

 

My oldest dog digs/buries his food all the time. I think it's just their way of protecting their food from others eating it.

 

I have never seen Candy bury any bones but she is forever digging holes. Even in the cement floor. Maybe she is looking for bones.

 

And when is the time that he gets back for his food and were there occasions that he guarded it?

 

Now that I think about it, I did have an old male Shih Tzu that was very possessive about its food. It wasn't able to eat everything at once but it would hoard the best bits for later. It would just put it right next to where it slept. Woe befall any other dog that thought of sneaking a bite.
