My dog bit someone. Why is he panting and breathing fast now?

Hello, although he must have been very stressed during the episode, its unlikely that he continues to be stressed now. He could how ever be breathing like you are describing due to pain especially if Max was seriously injured during the encounter. I would recommend having him assessed to ensure he does not have any serious or painful injuries that would require medical management. Hope this helps and best of luck!!!

Is he on pain control? I would recommend following up with a veterinarian if he is still acting like this. He may need a different medication or more medication to make him feel more comfortable. Thank you for using Petco Pet Education Center, formerly Petcoach.

I would recommend to monitor him closely for the next 4-6hours in case signs become more consistent. The presentation you described should not be a problem at all, especially if there are no other signs with it.

These are vague signs that could indicate several things like anxiety or pain. If there is something they could be making him anxious (rain, thunder, fireworks, new people, etc), then he will calm down afterwards. Just give him some extra attention. If there is nothing you can think that is making him anxious he could be in discomfort. I would have your vet do an exam to make sure he doesn't need any pain medication. I would not give net human pain meds as most of these are toxic to dogs. I hope this helps!

He probably suffers car/bus trips and he is likely to feel sick; he may vomit any time. I would suggest to withhold food for the next 8-12 hours and then start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 24hours. I would definitively recommend a veterinary check up if the signs persist or you notice diarrhoea, vomiting, lethargy or inappetence. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

That is not the type of reaction I would expect from a bug bite. I would be concerned about pain first and foremost. If she's still pacing, panting, or acting erratic, I would recommend taking her to a vet right away for evaluation. They will likely do a physical exam and take some x-rays, maybe run some blood work. I hope she's feeling better soon!

I think that with any abnormal behavior you should call your vet for advice since they knew all that went on. I'm assuming he is taking some medications? The excessive panting could be from that. I think you should just check in with them to be on the safe side!
