I understand you are in a difficult position as your Dad is paying the Bills. Is it possible for you to put some money toward the fees? even if it's $10 it shows you are commited and serious.
I know you all want a dog, but responsibly owning a dog and meeting it's needs means a lot more than having a dog in your yard.
He needs training Mason, esspecially as he is a large breed. He will also need desexing at an early age (before 6 months) this will also help him settle and his dominent behaviour will soften.
Ring the vet, get the cost of classes and ask what training you will work on, when the classes start etc.
Then sit down with your Dad and ask for his support.
Focus on the great benefits of training and how you will all benefit as a family.
Tell him this is important and that you are prepared to do the work.
You have all decided you want this puppy, and now you need to follow through in responsibly addressing the issues.
Animlas are not a disposable commodity, they are a lifetime commitment
I had better not comment much on the Backyard Breeder responsible for this litter other than to say i hope he never breeds again. He has absolutely no idea of what he is doing. I would love nothing more than to drag him through the pound and show him what people like him are responsible for. Argggh
He has sold your puppy weeks to early and as a result he has missed out on crucial socialisation with his Mum and siblings. This is why you are now having so many problems Mason.
Anyway, let me know how you go ok! do you think your Dad will listen to what you have to say?
