My half-retriever furbabe is depress

Hi everyone! Chewy hasn’t been eating well for the past four days, so we decided to bring him to the vet for a check-up. After his blood and stool tests, he suddenly had a burst of energy and even ate the treat the vet gave him. 😅 The doctor thinks he might just be frustrated since it’s mating season and he can’t really do anything about it. Has anyone else experienced this with their furbaby? 🐾
