Why is my dog's leg swollen, and he's not walking or responsive?

I don't know what type of research you did but i would not be able to tell by the bite if it is a venomous snake or not, i strongly recommend taking him to the emergency right away as a snake bite can easily be deadly within a few hours.

I can see the swelling from the pictures you posted. It appears the swelling goes form the foot all the way to the knee. I see that you live in an area where snake bite is possible. I would check thoroughly for any punctures along the entire leg and see if Diamond is painful in any particular area. If not, other causes of swelling like this could include infection, allergic reaction, trauma, cancer, among others. Sometimes swelling in an entire limb can be caused by decreased lymphatic flow - this can be caused by damage to lymph nodes or a structure under the skin or inside the body that is impinging on the lymph flow. I have also seen swelling like this with a flare-up of a mast cell tumor elsewhere on the body. I agree with your vet; if the medications prescribed to not make a difference, additional diagnostics are warranted. They may include bloodwork, abdominal x-rays, tick testing, or sampling of any small masses found.

I would take Casper into a vet today. He sounds painful, which is why he won't walk on the leg and cries when you touch it. He could have injured it, broken a bone, or torn a ligament. He needs to see a vet now to see what is causing the pain so he can be treated. The vet can prescribe pain medications as needed. Please do not give him any human pain medications, as many are toxic to dogs and can be fatal if given. Best of luck.

If it was a poisonous snake, then it would cause a great deal of swelling, so I wouldn't worry too much about a dangerous snake bite. There are some nonvenomous snakes there that can bite and cause pain, but they are usually not that bad. I would suspect that something else could be causing the pain. It could be an injury to a muscle, tendon or ligament. It may be OK to wait a couple of days to see if it gets better. If Rocky is otherwise acting normal and you don't see swelling, then it likely won't hurt to wait it out. It really depends on the injury though and it's difficult to know without seeing Rocky. In the meantime, you can ice the sore leg for 15 minutes twice a day. This may help.

Hello, sorry to hear about Al. He can have up to 160 mg of benadryl every 8 - 12hours. I would increase his dose to 80 -100mg every 8 hours and see if that helps decrease the swelling. Otherwise, you may be able to be seen by Virginia -Maryland School of Veterinary Medicine since they have a 24h emergency room. That is located in Blacksburg. You can also try to ice the leg to decrease some of the swelling. Hope this helps and best of luck.

Hello. While it is possible that Nona was bitten on her foot by something, she could also have a more serious problem- like infection or even broken bone in her foot. I recommend taking Nona to your veterinarian. There they will be able to do a physical examination to find the cause of her injury and at least give her a pain medication. I hope this helps!

This looks like a severe bite wound and it would need to be examined by a veterinarian. This wound needs to be cleaned and disinfected and your dog will need pain medicine and antibiotics, Please take Tyson to a veterinarian for wound care. The swelling may be a sign of a fracture or infection.
