Q. My dog has been acting excessively hungry lately. He's been licking everything and trying to eat everything.
A. I would firstly make sure he has been wormed with a good quality worm treatment from your vet in the last month. The over the counter ones are not as effective. If you have already done this then I would next look at his diet to ensure that it is a good quality balanced diet so that he isn't lacking in any nutrients. If all of these are ok and it has been going on for more than several days then you can have him examined by your vet and maybe some blood tests done.
