• My puppy’s breath started smelling like fish yesterday and he hasn’t been too interested in eating today? He is also a little more lethargic. There has been no change in his diet and nothing foreign is known to have been ingested. Thanks in advance.

    Hi John,
    If these symptoms have continued I recommend that you take him into see a veterinarian as soon as possible. The breath smell change along with the lethargy and lack of appetite is concerning. This can be a sign of an infection or injury to the mouth but it can also be caused by a serious underlying medical issue like diabetes or kidney disease. Your vet can talk to you more about the cause of his symptoms after they have examined him. They may recommend some lab tests to help diagnose or rule out certain diseases. The treatment that he needs will depend on the underlying cause of the symptoms.
