My dog Lincoln is 3 months old and as long as i've had him he has been a great eater. However, within the last two weeks, he has had a significant drop in the amount hes eating. He will just sniff his food and walk away. I have started to mix his food with a LITTLE bit of juices from a wet can of dog food but I really didn't want to start him on the mixture since he was doing so well with just dry food. Any suggestions? Also , IF recommended that I start a dry/wet food mix can you guys recommend a high-quality wet food for dogs? TIA!
