I have a toy french poodle and I started giving her Kibbles n’ Bits for a while now. and she loves it, I also mix it with the pedigree champs wet food. She loves it but I started doubting the dry food and wondered what food could I get for her that was at a reasonable price?

I have a 2 year old red toy poodle. I was wondering what would be the healthiest dog food for her (i.e., Eukanuba, etc.)?
Thanks,
Todd
PS: The dog is healthy, with all her necessary vaccines and shots, and she has no worms nor diseases… in case that helps pinpoint the best food for her.
