Hi,
I’d start rotating your dog foods, so he is getting a variety of different ingredients, this strengthen their immune system & later on he can eat anything & no dog foods will be too rich (High in Protein) for him..
When you rotate between different brands, if he’s eating a brand that isn’t balanced properly then he’s not eating it long enough, to cause any health problems cause you’re rotating his foods..
* Look at Freeze Dried foods, Raw Coated Kibble, Air Dried Raw etc
I’d stay away from kibble or try not feed him just dry processed kibble…
introduce a variety of different foods…
Dogs have a short digestive tract made to digest a raw, low fiber diet, not these high fiber dry kibbles full of lentils, sweet potatoes are good, low in Gi…

Click on link below & watch Stella & Chewy video & their new Raw blended baked kibble & their Raw Freeze Dried Patties look good, you add water, scroll down bottom & look at all Stella & Chewy’s different diets.

But I did notice the raw freeze dried coated kibbles have Chickpeas & Lentils, so this is when you rotate between different brands & the next food you feed doesn’t have any Lentils or Chickpeas. When the bag of dog food is nilly finished & there’s 1/4 of the bag left you start introducing another new brand of food with his old food & introduce, once his immune is strengthen from rotating different dog foods, you won’t need to slowly introduce new foods…..
You’ll see which brands he does really well on then use these brands in your rotation… I feed 1 brand for breakfast & lunch & something different for dinner…

*Have a look at “Canisource Grand CRU” Dehydrated Raw balls
you can add warm water wait 15 mins so the balls rehydrate or add some yogurt or kefir as a topper..
