my black lab chesapeak bay mix is four months old. when she was of age she had her HIV, distemperment, and Parvo shot and she was wormed too. she is usually really hyper to see us and everything but she has been really calm and not eating or drinking much. she dosent like to walk if she can help it and she sleeps all the time. she has runny stuff from her eyes, a lot of it it is grayish whiteish and sticky. can you please tell me if you know what is wrong. can she sleep it off or do we need to get her to a vet immediately?
