You would be surprised how many purebreeds or first crosses one can find. He is five or six. A first cross dogo argentino. Is not microchipped. I found out he has been wondering the streets for at least a few months, as know of a woman who fed him and treated his wounds in November. Due to his scars we believe he was used as a fighting dog. But, he is extremely gentle and kind, he wags his tail at my dogs and cats and does not seem at all agressive.
You are right, due to his breed and history he will need someone that is familiar with this breed and has the time to dedicate to caring for him properly. The dogo argentino is supposed to be a very loyal breed, excellent with its family and children, but they make a strong differentiation towards strangers, which is why they make good guard dogs.
I am attaching the photo of when I found him
and a photo of a few days later at my house.
If you are familiar with this breed please get in contact to try to save him.
