Hi and Welcome to YT!
Sounds like he may have Separation Anxiety. Have you tried leaving the radio or TV on for him when you leave?
Add some Royal Canin to the homecooked food, and gradually over two weeks or so, add more and more of the RC and less homecooking. Only feed him his dinner in his food bowl, no scraps from the table, and any treats away from the table. Do not give him any table food after the switch is made, except for some yogurt or cottage cheese (can top his food to entice him to eat). Keep us posted on his progress! |
