It may just be his coat, so I’m seeing it wrong, but he looks like he may be a little overweight. If he is, and it’s affecting his joint health, he may be off his food from that. But like I said, could just be his coat making him look larger than he seems in the pic.
3 out of 4 of mine scarf their food down in about five minutes. Our GSD/Husky is a PITA, and sometimes won’t eat at all in a day. Sometimes he eats like he hasn’t been offered food for a week. My routine is fill the 4 bowls with the varying portion sizes, and place Lyka’s bowl down first, then Crios (the GSD/Husky), then Floki, and Seiran last. They all have to sit, watch me, and stay seated until the bowl is down, then they can eat. I watch Seiran and Floki to make sure they aren’t crossing bowls, and then go collect Lyka’s bowl, and Crios’s bowl. The process takes about 20 minutes. If Crios hasn’t eaten a single piece of kibble, I still pull his bowl and offer it at the next meal time. We’ve tried both toppers (salmon oil, yogurt, chopped boiled eggs, rinsed sardines, pumpkin and bone broth, still won’t eat it). So we stopped trying the toppers, it’s wasted food, we can’t offer it to him again at evening meal time if it’s been sitting around with toppers.
Him and Lyka used to free feed until we got the pups. Lyka learned quickly if she wanted a meal, she needed to eat it then instead of picking throughout the day. Crios is a stubborn dog, and goes on food strikes because he doesn’t like me timing his meals. I don’t worry about it. He’s still a very healthy weight, and he does give in when he’s really hungry, so I’m not changing a thing.
We are going to try a slow change from Fromm to Victors, but even switching flavors of Fromm didn’t have any affect on his stubbornness. We are switching for one of the pups that is having weight issues.
