There is a good sticky here, called the Cost of owing a dog. The first year is always the most expensive, because it usually includes the cost of a spay, and their third set of shots, and of course, the beds, crate, and xpens, toys, and leashes you get for your pup.
I shudder to share with you what I spend on my boy. Because he is totally spoilt and to boot a show boy. Plus I do raw feed my boy, and spend lots on supplements etc. How-ever I groom myself which is a cost savings
But then again I have every shampoo and conditioner under the sun too
Then I train him, do agility and obedience, so it all sort of blurs out.
Look at that sticky. But do add in the cost of a warm coat for your pup in the wintertime, (if you live in a cold climate). Not so pricey maybe $20 or so.
Wheither you send your pup to the groomer or not, you still will need to do some grooming yourself ... so brush n comb at the minimum, and if you want to do grooming yourself, blunt nose scissors, clipper, straight scissor, and a dematter.
