Why is my dog so tired after taking prednisone for allergies?

Updated on September 23rd, 2025

Pet's info: Dog | American Pit Bull Terrier | Female | spayed | 10 months and 11 days old | 48 lbs

Lua is taking prednisone (10mg) for the first time for an allergic reaction. She has been taking it for 6 days. She is very lethargic and just laying around all the time. Is this normal? She is eating and drinking. Not her normal bouncing off the walls self.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Lua. Yes, a general loss of energy is a common side effect of prednisone. This should pass after she goes off the steroid. It's good that she is eating and drinking, and I would continue to monitor her. I hope this helps!
