If he doesnāt like rice or he is sensitive to rice(some dogs are allergic), beef and sweet potatoes, OR chicken and sweet potatoes(instead of rice use sweet potatoes).
Yes you need to add meat, dogs need meat, thatās one thing they require and the most beneficial to them.
Either chicken or beef is good to use.
So yes every time you feed him, use meat.
For example when I was cooking for my dog, I would cook 3 days worth and portion it out into 1 day portions, it already has meat in it if you cook meat and sweet potatoes(just as example).
I cook beef on the stove in a pan until itās cooked, however you like to cook beef or chicken, cook it like that and make sure there is meat in what you give him.
When I cooked for my dog, it was 75% cooked meat and 25% carbs(sweet potatoes). I used that as example because thatās what i was cooking for him, every day for months until he got tired of it and got picky, he likes more variety
So they definitely require meat, thatās what gives them the amino acids they need and the protein and fat that they require.
The sweet potatoes I cooked in oven, peeled and when ready, mix it up with the meat in a bowl and then feed it to him.
Do at least 50% meat and 50% sweet potatoes, no less meat, but I recommend the 75% meat and 25% sweet potatoes or rice.
If using beef, use extra lean ground beef. If he lies chicken and isnāt allergic then try the chicken.
Pumpkin can be mixed in too.
