wet food or dry food for old dog?? (kiki 10yo)

Kiki is 10 years old now and she has less teeth, so the dry kibble is harder for her to chew. I started giving her wet food about 3 months ago and she loves it, but the vet says not to switch everything at once because her stomach can get upset.

My mistake the first time: I put the new wet food in with the dry and mixed too much, she ate only the wet part and left the dry, then I was worried she was not eating enough. So be careful how much she eats.

What I do now: morning is dry, dinner is half wet and half dry. Wet food stays in fridge max 2 days, I heat up a little bit so it is warm, not hot. Also make sure water bowl is full because wet food is not the same as drinking water, Kiki still needs to drink.

Some people say wet is always better but the vet told me it depends on the dog. Wet food is more expensive too, about double the price per meal for us. So for now we do the mix.

I am still not sure it is good for her long term, so I will ask the vet again at the next check up. Kiki is happy though, she wags her tail when I open the can.
