He is a 10 month old lab cross. In the last week he has decreed that sleeping at night is optional. He whines, cries and barks. He is healthy, not hungry, didn't need to toilet,just wanted to be awake . I think the fireworks for the last week didn't help. Vet nurse suggests benadryl for the next 2/3 nights to get him back in routine. We're on our knees. Anyone tried it ?
