Get Your Dog Care Questions Answered by Experts
Hello, I see this question came in earlier. How is your dog now?
Is the dog limping or walking differently?
How old is the dog?
Is the dog eating and drinking okay?
Any vomiting or diarrhea?
Any scooting on its rear?
I think you should take his vital signs to make sure you do not have an emergency on your hands. Check his gums and capillary refill time as well as his temperature. I am going to direct you to a link that will tell you how to do all of this as well as what is normal.
IF he has low energy there may be an infection somewhere that needs medication.
With his actions and his age and now the low energy I feel a visit to the vet may be warrented if nothing changes.
