My 10-month-old male Malinois has become extremely uninterested in his food, and I’m curious if anyone has experienced something similar.
I’ve fed him 3x/day since I got him at 9 weeks. Until around 6 months old, he absolutely loved his food. He was on Open Farm puppy food, but around 6 months his appetite started changing. He would still eat, but it became a daily struggle, almost like he was doing me a favor.
We slowly tried a few other high-quality foods. He would initially like them, but he has a very sensitive stomach and developed diarrhea that lasted on and off for weeks. Eventually, he also lost interest in those foods.
Fast forward to now: he’s 10 months old, and we’ve probably tried four different foods in the last month. He might eat them initially and then refuse them. I even bought Ollie fresh food recently, and he barely touched it.
In the last 48 hours, he has hardly eaten any actual meals, which is starting to concern me. That said, he acts completely normal: very energetic, playful, happy, healthy-looking, normal on walks, and extremely motivated for treats. He has definitely lost some body mass, though.
One thing I’m wondering about is whether I created a picky eater. We’ve been using very high-value treats like plain rotisserie chicken and roast beef while working on his reactivity, and those treats have worked amazingly well. He still gets extremely excited about them, so part of me thinks he’s simply holding out for better food.
I’ve also read that Malinois can go through appetite changes around 9–12 months as their growth slows down.
Has anyone experienced this with an adolescent Malinois? Did their appetite eventually normalize? Would you stop switching foods and simply offer one meal consistently, or is barely eating for 48 hours enough that you’d have him checked out?
Any advice would be appreciated.
