Anyone here make their own dog food?

My vet at that time was against anything other than commercial dog food. He said that is what they need for every meal and nothing else... not even treats.
My two Shih Tzu did not agree with him. Lol. They got bored with their food. I would give them a few tiny cubed of steamed carrots or sometimes lima beans and sweet potato. Occasionally my wife would cook chicken breast in the crock pot. They loved that.
I was always told to switch any foods gradually but my two wouldn't do that either. If I tried by adding a little new food with their old, they would eat only the new stuff and leave all the old.
Last January, I noticed my 16 lb. Belle had lost some weight. She was diagnosed with an enlarged heart and grade 4 (out of 6) heart murmur. She kept losing weight, so I was trying anything to get her to eat. Chicken breast, hamburger, bacon, sometimes a pinch of bread, steamed veggies, and she would eat each one time and then she didn't want it again for days. By August, she was 12½ lbs. Her heart was bad and her kidney values weren't good, so I had to let her go.
Looking back, I wish I had given them more good stuff all along. They would eat their kibbles too if I flavored it up a little.
