My dog's stomach hit by door. Could there be internal bleeding?

Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! In theory any sort of blunt trauma on the abdomen can cause internal bleeding. However, in reality, it requires a good amount of force which from your description it does not seem to be the case. I recommend you keep a close eye on Jax for any signs of bleeding or just any traumatic injury from this event. Signs you would watch for include severe weakness, lethargy, pale gums and/or collapse. If observed, having examined right away. If he is fine after the next 24-48 hours, in all likelihood he will be just fine. Good luck with your boy!

Typically no this cannot cause internal bleeding. It would take a severe blunt forced traumatic event (stabbing, hit by car, falling off high surface, etc) to cause internal bleeding in a pet. However, with that said I wouldn't push your luck and just start poking your pets belly just for the sake of doing so.

Jim could still have been hurt from the door slam without a cry because dogs are stoic and sometimes do not display vocal signs of pain. That being said, however, as long as he is moving around normally and behaving normally, he is likely just fine.

It would depend a bit on how hard you poked him, but in general I would not expect this to cause any serious problems. As long as Jim is acting normal and there is no bruising or other sign of injury on his stomach, I wouldn't be concerned.

It's hard to tell from the pictures, but it looks like there might be a small puncture near the bruised area? This would mean that Rosie was bitten on the abdomen. These types of injuries could be associated with internal damage, and should warrant immediate veterinary care. If there is no wound, then I would still be concerned about the sudden appearance of a bruise. Bruises can form if there is a bleeding or clotting issue or internal bleeding.

It can be difficult to tell for sure if your dog is in pain, however I'd have to say given the recent events (the door slamming on him) and his inability to settle (wandering the house) it's likely that he is. Hopefully he sustained just a bit of muscular trauma that's leading to soreness, but if he isn't completely back to normal at this point (i.e. he's comfortable and you can easily pick him up and interact with him without him showing signs of pain) then I would for sure take him in to see his vet, as he could have broken a rib, and that injury can have serious consequences, such as puncturing lung tissue.

The stomach can get hard from internal damage or severe pain. if Jax seems to have a hard stomach and he isn't himself then you should take him to the vet ASAP in order to get it checked and make sure he isn't injured.
