I wouldn't get another puppy until you have a lot of money saved up & a credit card so you can be prepared for any emergancies in the future. As you already know you couldn't afford Tinks last vet visit. I'd say if you have a few thousand saved up you should be off to a good start. Heck you'll spend about a thousand just in the first month, on the dog, supplies and first vet visits.
I agree with this totally. You couldn't afford the vets bill, but you can afford to buy another "pedigree" puppy right away? I don't want to put a damper on your excitement, but nothing can survive only on love, money is important too.
