I have a healthy trim 5 yr old Black Lab. This past Friday I notice she had a slack look to her jaw and she was drooling. Almost appears she can't use her lips or something. Went to vet, couldn't identify problem. Doing facial massage, heat therapy, drool is thick and foamy like whipped egg white. Excessive, constant...I'm very worried. She has healthy appetite, no fever, but isn't right.
If the problem is not better then I recommend a follow up with your veterinarian. I am sure your vet will want to know how your pet is doing and may have other suggestions for diagnosis and treatment. vetcare
