Weeks ago the leg of my 5 years old boxer was very swollen and he even walked a little limp, time later a kind of wound was formed and until today it has not been removed.

Thought my dog does not complain about anything, does not cry, or anything, keeps eating well, runs without any problem now, and everything normal. Although from time to time I've noticed that he licks his leg.

What could it be? Is it a disease? Could it be dangerous, contagious, ... ?

Should I take him to the vet?

Or will it heal with the passage of time?

Thank you in advance for your help.

Here is the picture (apologies if it looks really bad)

I know you have mention in the answers to take my dog to the veterinarian and I do really want to take him asap but vet is on vacations and won't be here until January. So please tell me what can I do to help my dog for now? Should I bandage his leg? Something else?

I took him other photos recently. Does it looks better? Please help me

2nd update

I luckily could contact the current vet and told me it is a skin fungal infection. And vet recommended a cream.

It's an untreated wound that should be seen by veterinarian. Only a licensed vet can reliably diagnose what kind of wound this is. If the dog continues to pay attention to it it clearly still affects the animal and further long term damage or harm should be mitigated as soon as possible.


Does he naturally have black skin? It looks like he does but it is difficult for me to tell. I was worried about necrosis, but which would occur from a spider or infected wound. However, for it to be that, it would have to be infected a long time. The bite does resemble that which are left by the chelicerata of a spider. It also could be an allergic reaction. If he's licking at the irritated area a lot, that would account for the hair loss.

  • Yes, well in his 4 legs has black skin. I don't think it could be an allergic reaction since he had been a healthy dog (in this 5 years this is the second time something bad happen, the first one was a flu when he had approx. 1 year old). Indeed it looks like a bite. Do you know of any kind of home remedy for this case? Dec 26, 2018 at 16:10

Well it could just be an abrasion, a scrape from falling down. Or it could be cancer, worst case. Or probably a dozen other things (none of which are that risky to a healthy human - but wash your hands). One can't really say for sure from a visual inspection. Given that it has been there for weeks, if it was just a scrape then it may be infected. You might have to cone the dog if it licks the wound a lot and makes it worse. Could also try Neosporin antibiotic ointment. A veterinarian is the way to go.

Our dog currently has a long lasting wound and getting it checked cost about $150 :( Vet did a biopsy, we put some creams on it. Still not 100% sure what it is.

  • Thank you for your reply, I think I'll definitely take him to the vet (though one of my neighbors said the injury is healing and looks better now.. I honestly don't see the progress so the vet is necessary) Dec 24, 2018 at 19:30
