Considering your dog’s issues I think Abady granular would be worth looking into. It would be a great food for putting weight on a dog – it’s high fat with around 800 calories per cup (about twice as many calories per cup as kibble). I’ve also heard dogs with sensitive stomachs do well on it.
Wet food is definitely a good addition to dry food, but it wouldn’t help much as far as adding calories. Due to its high moisture content wet food is generally much less calorie-dense than dry food.
I had issues getting my female bloodhound (now two years old) to gain weight and it wasn’t until I switched her to a high protein, high fat, low carbohydrate homemade raw diet that I got her to gain anything (she’s still skinny but looks a lot better than before she was on raw). She eats 2 lbs. of meat per day with extras – such as eggs, cottage cheese and kefir – plus supplements and veggies and I was able to get her to put on 5 (much needed!) pounds after three months on raw and now she’s maintaining nicely. I aim for her meals to be 40-50% protein and 30-40% fat. So if you’ve got the time and money a high fat homemade diet would probably be the best option. The other benefit of homemade is you can tailor it to the needs of your sensitive dog since you control all the ingredients that go into it.
