My dog is lethargic after pain injection for injury. Is this normal?

Updated On September 23rd, 2025

Pet's info: Dog | Staffordshire Bull Terrier | 8 years and 6 months old

My dog has had an injection for pain relief this evening as he has a possible slipped disc or ligament injury, we have oral pain relief too for the weekend .. He is very lethargic since the injection, is that a normal side effect? . He's not interested in any food so there's no chance of him taking any tablets. He doesn't want to get up . Could it be the effects of the injection Many thanks in advance

It is impossible for us to predict if this is a normal response to a sedative / pain medication, progression of the condition or a different issue entirely without knowing exactly how much and what type of injectable pain relief he was given. I recommend you contact with the vets office and inform them of the change in his status and they can confirm id this is a temporary and expected response to a strong opioid pain killer or if he needs to be reassessed
