My puppy yelped, limping, stomach weird after I sat on him. What to do?

I would definitely take him to see your vet. He may have a hidden injury, the shifting lameness could indicate a condition affecting his bones called panosteitis, which is seen in growing puppies, usually large breeds. Since he's feeling poorly overall, I think the sooner he sees the vet, the better. Your vet will do an exam, probably labwork and x-rays, and based on these results, will be better able to inform you about your dog's condition and how best to treat it.

Oh no, poor Lioh! I see your post was about six hours ago, and if Lioh is in pain, having trouble moving or breathing, or is very lethargic, then I would have him seen by an ER vet immediately. If there isn't an ER vet clinic in your area, then there will be a vet on call for emergencies. The information to find that vet is found on a clinic's answering machine or website. If Lioh is behaving normally, eating and drinking, and going to the bathroom normally, then he is likely fine :-)

It would be a good idea to have your vet do an exam to determine the cause of his pain and if treatment is needed. He may just have a soft tissue injury and your vet could prescribe and anti-inflammatory to help alleviate his pain.

He should be seen by a vet right away. Even though he is moving all of his extremities well, he may have internal injuries that need treatment. He could have a slow bleed, rupture of an organ, etc. Medical attention is very important.

It's possible that he just sprained or jammed something. I'd let him rest for a bit but if he continues to be painful or won't use it then get him seen. He may have a fracture or dislocation if he hit hard enough. If he's crate trained out him to rest in there for a bit to see if he settles. Do not give otc medicines for pain!

Oh poor finn!! This is such a common occurrence with young, excitable puppies. If he is just limping slightly and able to bear some weight I would just allow him to rest and give him 24 hours to see if the limping resolves. If he can't use the leg or if limping is persisting beyond 24 hours I would have a vet evaluate him. I hope we wakes up from his rest feeling better!

If she isn't feeling well and just laying on you then I would take her in. If she is comfortable and otherwise ok you can wait until tomorrow but if she won't walk, very lethargic or seems painful I would take her now. A veterinarian can see if x-rays are needed and provide medication to make Rosie feel better. Thank you for using Petco Pet Education Center, formerly Petcoach.
