Don't buy canned dogfood.
It's expensive and not that good for your dog
buy inexpensive cuts of meat and put in the effort of cooking some up ever 2 or 3 days
consider these things which are cheaper tham dogfood:
chicken livers, chicken hearts, cube steak, ground chicken, ground turkey, chicken thighs.
always cooking it is a habit to get into but it's not a big deal.
Also...i have a fam of 5...sometimes it's cheaper to buy a lot and portion off some for the dog that will not be spiced.
be aware that they need more meat for a serving than dry dog food be suse dry dog food bloats up in their stomaches.
you can add rice with meat juices if you're low on meat but no potatoes.
