I got my puppy his first round of shots. Any idea on the maximum I can wait to get his second. Low on cash thanks?

FOUR WEEKS and if after that they make you go back to the beginning.

However, if you had the first done at your vets do check because most vets charge for the course ....ie... the 8 & 12 week vaccines in one go.

Also as Belgian says, if you can't afford the basic vaccine course then you really cannot afford to keep a dog. Vet bills run into the thousands often.

Four weeks. And if you can't afford basic vet care, you have NO business getting a puppy. Return it. There'll be more expenses, lots of them, throughout the dog's life.

It should be done within 3-4 weeks of the last shots.

Hmm! Ask the vet
