What to do if my chihuahua hit her head and might have a concussion?

Concussions can be tough to diagnose and can be very serious (just like in humans). Here is a link which may help: https://www.petcoach.co/article/concussions-in-dogs-what-you-should-know/ Without knowing the cause for the abnormal behavior, it's difficult to know how to treat him or if home care is even possible (just like humans, sometimes a doctor's care is absolutely needed). At home you want to make sure he is protected from harm such as falling down the stairs. You should make sure he is eating and drinking (you may need to bring him the bowls and hand feed him). There may only be so much you can do and there may be treatment he needs to avoid further complications. To be safe, I recommend to have your pup examined.

If Eriko isn't showing any other signs since her fall 13 hours ago, I would just continue to monitor her. She may have been pacing because she was in pain. Continue to keep an eye on her, and if she develops any concerning signs or starts pacing again, have her seen by a vet. Best of luck.

If she is remaining sleepy, has poor balance or vomiting I would be concerned about a possible head injury and recommend she be assessed by a vet as soon as possible. Otherwise continue to monitor for food and fluid intake and ensure no rough play for the next 48 hours

Vomiting after an head trauma might be concerning. I recommend to bring her to the vet for a physical and neurological examinations to exclude brain damages (i.e. concussion). Please post again on the forum if you would like to discuss it further. I hope my answer was helpful.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Bella. Poor girl. This would not cause a concussion, it would have to be something very heavy. I doubt she needs a vet visit. She will be fine. I hope this helps!

Poor little Reggie. Since he's acting normally, I'd keep an eye on him for now. If you notice him getting dizzy again, has blood coming from his nose or ears, confusion, disorientation, difficulty walking, or abnormal eye movements, have him seen by a vet immediately. Otherwise, he should be ok.

Hello. Max may have really bruised his head, or may even have a mild concussion. You will need to decide if his behavior is really strange & worrisome & this warrants an emergency visit. If he just shakes his head every so often & otherwise seems fine, then he should be OK. See how he is in the morning & if he still seems to be bothered by the fall, do have him evaluated by a veterinarian. Thanks for contacting Petco Pet Education Center, formerly Petcoach.
