My puppy is whiny, sad, low energy, and chewing. Is he teething or sick?

It is difficult to know without examining him. He could have a problem with his teeth or maybe he is nauseous from an upset stomach. The best thing would be to have him examined by a vet to determine if he has a problem and then treat. If he is experiencing pain, your vet can prescribe an anti-inflammatory to help relieve any pain and inflammation. If he is having stomach/abdominal issues then he may need an anti-nausea medication and a gastrointestinal protectant.

Young puppies will whine or vocalize when cold, hungry, sick, injured or if left alone for long periods of time. You can make sure he is fed, warm and has company. To diagnose illness or injury, he would need to be physically examined by your veterinarian.

It sounds like something is definitely going on with Sushi. Inappetance can be the first symptom dogs show that tells us they are not feeling well. Also, since his behavior today is not normal for him this could be an indication that something is wrong as well. It is unlikely that teething is the problem because dogs do not usually have any issue with this. If Sushi does not eat for more than 24 hours, or if he begins vomiting and/or having diarrhea, then I would recommend taking him in to be checked out by your vet.

Hello, depending on how long this has been going on you may give him more time to snap out of it. If he continues to be sad for longer than a day, or if he has a decreased appetite, vomiting, or diarrhea, then you should have your puppy seen by a veterinarian. Hope this helps and best of luck,

Cub is such a cutie! I'm sorry to hear he is not feeling himself. If he is crying and has a poor appetite, I worry that he is in pain somewhere. His behavior toward your other dog may be his way of showing stress. I would definitely recommend that he be assessed by your family vet soon. I hope this helps, and your little pooch is feeling better soon!

Poor Poofy! If the lethargy and weakness continues, he should be examined by a vet to determine the cause. He could have an infection or parasite and your vet can run some tests to help diagnose and then prescribe medications to help.

It is normal for dogs energy to levels to decrease slightly as they age. You should consider if Calhoun is still interested in the same activities, or if he no longer plays or gets excited for walks, for example. You know Calhoun best, so if you are concerned that he seems "off" I recommend having him seen by a vet who can perform the appropriate diagnostic tests. I'm happy to answer any additional questions you may have!
