My dog's paw has a fleshy lump and she keeps licking her broken nail.

Thank you for using Petco Pet Education Center, formerly Petcoach! While it is hard to say exactly what is going on without seeing a photo, it is possible that Devon somehow broke his nails. The blood you are seeing may be due to the quick, or the small blood vessel that runs through each nail being exposed. This is pretty painful and can be why Devon is constantly licking. I recommend getting him an E-collar or “cone” to prevent him from licking and causing further trauma and having him seen by a vet who may prescribe pain medication. I hope this helps!

I would be hesitant to do anything at home as it may be too painful. The dark part is likely old blood and discharge over the nerve part the shell protects. The shell is displaced exposing thisbtissue. Often times they need to be sedated to have it cleaned and trimmed back past the break to get to healthy tissue. You can try to soak it warm water to see if you can clean up around hr nail and get the discharge gone but it may be too painful to do. I would get him to your vet for this when you can

It may be split deeply and hurt a bit or otherwise bother your dog. This is why Walt is licking it There also may be a nailbed infection. I suggest you take Walt to your veterinarian for an exam. Your vet can check the nail for a fracture, infection or injury and help so that it does not bother your dog so much or hurt. It may need to be clipped or removed to aid healing. If you have an e-collar at home, put it on Walt so he cannot lick more bacteria into it. Please schedule an exam with your vet.

That is what is known as the quik of the nail. It the sensitive portion that contains the nerves and blood supply. The nail have been broken and the protective shell has been separated from the quik. It is painful and can bleed a lot. Typically they have to be sedated and have the quick trimmed back so it will not be exposed further and be painful to allow the nail to regrow.

It does look like there is some discharge/pus around the nail bed and I would recommend getting it rechecked by your vet, if confirmed she may require a course of antibiotics. Bathing the are in saline/salted water and drying carefully will help to freshen the area in the meantime. If she is very lame x-rays may need to be considered to rule out underlying factors behind the lost nail/swollen toe

It is very difficult to tell from these photos, it is possible that your dog's toe nail became slightly torn/detached from the underlying nail bed and you are seeing the separation here. We can, however, occasionally see nail bed tumors. I would recommend a visit with your vet to better examine the area. If it is a loose toenail they may need to trim it back to make it more comfortable until it grows back in normally. This can be very tough to do at home because often these guys are painful so trimming the nail back can be really difficult without skilled help!

Poor Paddt! Sometimes these nails need to be removed behind the break. It's hard to give you the best advice without being able to examined the nail. I recommend to have Paddt examined by the veterinarian. He should also be wearing an elizabethan collar at all times to prevent any licking since this could make the nail infected. The area should be kept clean and dry and the exercise should be severely restricted until the nail is healed (no walks, running or jumping). I hope this helps and please feel free to post any additional questions.
