Okay, so, basically I went to look at a puppy about a month ago and decided I was going to get him. 
He coats a fair amount of money, (especially for someone like me who doesn't have a stable income and relies on the state for money). 

I've been really good with holding myself back and waiting until I've saved enough money etc. As I said, it's only been almost a month now, but y'all know what it's like when you want something bad. We want it there and then. 

The time to think has been a positive. 
Instead of rushing into a decision there and then, I released I should save up more than what will barely cover the cost of a puppy. He will have to be insured, registered at the vet and have all the appropriate injections and treatments. 

It's frustrating, yes. It's the right decision for now though. I've got plenty of time ahead of me and plenty of time to get a dog when I've got a job and I'm financially stable. 

After researching online about breeders and what to look out for, I've been a bit scared off by the fact the advert specifically states the puppies will be vaccinated before they leave for their new homes. 
I've been in touch with the woman who's selling them and she said they've had their first round of vaccinations, but I'd have to get the rest done myself at a vet. This seems a bit strange to me, maybe I'm overthinking, I don't know. 

I've been to the home, seen the puppies and met the mother of the dogs. The woman who is selling them who must be in her mid twenties, along with her parents seem genuine and they have all the appropriate paperwork for the pups. 

Something seems a little off to me. I don't know what it is. Maybe it's purely because I've never bought a pup before and I'm paranoid. 
When she said about the vaccination being my responsibility, which isn't what the ad said, I started to worry. 



Anyway, that's enough back story. 

I've verbally agreed to get this puppy and I'm due to pick it up this Thursday, (23rd). 
Having changed my mind about the decision, I don't know what to say to the seller to avoid any serious confrontation. I have the right to say no, but I still feel bad about it. I have a very trusting nature and sometimes that leads to complications. 

My thoughts keep going from, "just say you changed your mind" to "say you've been in a car crash and have to keep the money to repair the car". I don't want to lie, but then it feels like any confrontation could be avoided with the car crash scenario. 

I'd really appreciate any advice or suggestions.
