<human>: Hello fellow redditors! 

I am not some person who is on a whim considering getting a dog this is something that I have been thinking about for a while. I am a qualified Veterinary Nurse, have several years experience working for the guide dogs and presently I am getting my degree in Canine behaviour and training. I already have a cat and a dog who is a Great Dane X German Shepherd. Both of them are rescues and my dog initially had behavioural issues. 

Today while out walking my own dog I ran into an acquaintance, a young guy about 19, walking his dog. I often meet him walking his own dog and as I was chatting with him he informed that he was walking home the other day when he was approached by a man with a German Shepherd pup. He said she was four months old and that he would sell her to him for €50. The guy, feeling he was doing the right thing, bought her as she was terrified looking. However, he isn't in a position to keep her and knew this when he bought her. 

I asked could I see her and he brought her out to see me. I reckon she is 4 months old due to her dentition but small due to malnutrition. She definitely has worms and is terrified of everything. I would imagine she has never been socialized properly. The man who sold her said that she was vaccinated but there is no way of knowing this really.

Financially I am struggling at the moment but I find it hard to turn my back on this puppy. I live in Ireland where the animal welfare laws are from 1911. The local shelters, who I work with, have no room as I have already checked. I need advice on how I should proceed? My heart says one thing and my brain another I would like some non biased opinions.

Give me a shortened version of the text
<bot>: Man bought terrified puppy on street, unable to keep her. Needs lots of help to become a well socialized adult which I have experience to help her with but I lack the sufficient finances should I do it anyway?
