I have 2 dogs, the rescue dog who we got last summer is approx 4 and has started to not really be too keen on eating his breakfast / dinner. He picks at it a bit and walks away, comes back picks walks away... This goes on for about 15 minutes and then he just leaves it totally. This has been going on for a few weeks, he sometimes will wolf the food down but now it's more often that not that he picks and leaves it as above.
I can't leave the food down as my other dog will eat it as soon as its left. I tried to entice him with a little bit of gravy on it but he wasnt really keen.
He has no problem eating his denti stick or other scraps that fall on the floor when I'm cooking, and his usual bouncy self so I don't think there's anything wrong with him.
Any advice how to get him back to eating to his routine?
