cost of a Rottweiler puppy
just wanting to know approx amount of money when buying a rottweiler...
That's actually a very difficult question to answer in any sort of concrete way because a lot depends on what country/region you are in and of course on what type of puppy you want.
A show quality puppy will cost more than one who is pet quality (and there can be only very subtle differences between show and pet quality, so you need to know what you're looking for).
Obviously a reputable breeder who has dogs with good pedigrees and lineage, who performs the proper health checks on their dogs and provides excellent care for the mom and puppies will have higher costs. This is then reflected in the price of the puppies they sell. However, buying a pup who has physically and mentally sound parents, and has been properly taken care of will generally save you a lot of money (and often heartache as well) in the long run.
I'd recommend that you take a look at my Choosing A Rottweiler Breeder and Rottweiler Breeders Directory to learn more about what to look for in a breeder. Do some research and visit the sites of the breeders shown and you'll get a better idea of what to be looking for and how much to pay.
Buying a puppy is a big commitment, both in terms of time and money, and it's not something you should rush into. Buying a pup is a big expense, but caring for him/her is a much more long-term and expensive project so being prepared is very important.
Hope this helps, best of luck.
