Dear Freshpet, I have 2 senior dogs. Chico the tan pup is 16, and Sam is 11. I drive a semi and they go everywhere with me. Sam has a very sensitive tummy and the vet had him on Royal Canin. They liked it, but at nearly $90.00 a case, i was looking for other options. Recently Chico was diagnosed with liver problems. I started cooking for them but to be honest with our schedule, it was tough!! Our new vet recommended Freshpet so I gave it a try.. They love it!! It's been almost 2 months now and we've had no problems!! Thank you!!
