Hi I'm getting my golden puppy this Friday, and I had a few questions to ask:

At what age should he get his shots and how much do they cost?
How many deworms per year and how much do they cost?
Should I neuter? How much will it cost?

I think it would be best to find a vet and ask them these questions because they would be able to answer about the costs and what vaccines are needed for your area.

Basics:
8 weeks old- Distemper/Parvo vaccine
12 weeks- Distemper/Parvo booster, lepto (maybe in your area?), lyme (again maybe?) and bordatella
16 weeks- Distemper/parvo booster, lepto and lyme booster, rabies

That is the protocol at my vet.
Be sure to take a stool sample to your first visit to check for parasites. Deworming is generally pretty cheap. Get your pup on a monthly heartworm regimen and that will also deworm them monthly for a few common parasites.

Neutering- there are lots of posts on that I suggest you search this forum. I am one to stay wait until at least 18 months to neuter.

The above schedule is the same we use down here in my area of Tx. too. Cost greatly differ in areas around the globe. Is is absolutely critical that your pup get all three of his/her puppy shots and be put on a worming schedule because there are many diseases that a young puppy can catch. Best bet is to call the Vets in your area for pricing and get your pup on his/her schedule first thing.

Just wanted to add to the above postings ....your baby is not safe from killer diseases such as Parvo until it has has all three vaccines & then a wait of several days. My vet advices ten days After third vaccination, before taking puppy out into public places & for walks. Some vets say four days is sufficient. It's really good to start some basic training at around eight weeks old, or once you have had your pup for about a week, to allow settling in. I did clicker training with mine, which I found really easy & pup trained up quickly ...great bonding time too, but don't get frustrated if puppy takes time to pick things up ...make it fun & keep it relaxed & lots of praise even if pup gets it half right.
