I took my dog to the vet and she had tonsillitis. She was prescribed prednisone and doxycycline. She’s been taking both for 4 days now and doesn’t seem to be herself (lack of energy.) She is still eating, drinking, and loves to go on her walks but inside the house she doesn’t seem as active and just lays around. Is lack of energy a side effect of any of these meds?
