I have tried every one of those dog foods for my little baby girl (13 yo Chihuahua Boston Terrier mix) so I decided to just make her food in my own kitchen. WE both eat the same thing at the same time. most the time ( about 85% of the time) she will clean her plate before I have had two bites of my meal. IT'S a lot cheaper and I know exactly what I am giving her. I also make almost ALL of her Treats as well. She Loves them and for a 13yo she actually acts more like a 2-3 year old. She always wants to play and run around outside.
Hi Michael,
Thank you for sharing! 🐾
It’s wonderful to hear how happy and energetic your little girl is, she sounds like a real joy. Cooking for her and making her treats yourself clearly brings both of you a lot of fun and connection, and it’s lovely that she’s so enthusiastic at mealtime.
Have a great day!
