Honestly, I would talk to your regular vet about it. Discuss what you’re feeding, how you’re feeding (type of bowl, frequency of meals), and ask their advice. They know your dog best and may have suggestions.
That said. I would worry very much about possible bloat in his future. I would invest in a slow feeding bowl and feed scheduled meals. If you don’t want to get a slow feeder, using an old muffin pan is an option worth considering. If you feed dry food, a food dispensing toy is a good option. I have a breed with a higher than normal likelihood of bloat due to chest size, and we opted for a Kong Wobbler for breakfasts and the occasional lunch (as she gets her breakfast dry) and a slow feed bowl for dinners. She is always fed 2-3 meals a day. She is never allowed to graze from an always-full bowl.
I would also look at activity levels around meals. Keeping a dog calm prior to and immediately after a meal is ideal.
Did they test her thyroid? A FULL thyroid panel, not just T4?
