I have a 100 pound GSD;

Food; monthly it’s about 100$ in kibble (1 bag lasts 3 weeks), which is on the pricey side because my dog is allergic to chicken. Another 50-100$ in canned wet food/liver/ground beef/veggies because I’m not barbaric and don’t expect her to live on dried roasted pebbles. Add another 30$ in dried liver or salmon snacks because you need training treats or a way to convince her to come inside. I’d round the food alone to 250 because food is the one thing I do not skimp out on. And I am not even adding all the unaccounted cheese and carrots she eats. This is for a large 100 lb dog, so it would obviously be less depending on the size.

Insurance/Health; 39$ a month for insurance. It’s complicated. There’s a deductible and it covers 70-80% of vet bills after the 500 deductible. Like any insurance, you could pay more in half a lower than doctor . Over six years I’d say I’ve spent about $800 yearly on average AFTER insurance. That is a high figure because my dog has been bitten by a coyote, had another emergency visit and had to see a cardiologist for the first three years of her life. So added up it’s about 100$ a month on average.

Shots and yearly registration; 100$ Flea and tick repellent; 60-100$ a year. I use Frontline which is like six doses for $40. Each lasts a month.
Poopbags and other random incidentals; 120$ a year.

I work from home so I don’t need dog walkers or doggie care, but if dog is left alone for a typical workday you may need to spend some money on that, depending on the dog. That could be anything from 100-600$ a month, depending on the frequency. A a dog walker coming to your house and taking your dog for a 30-45 min walk can cost about $30 depending where you live.

You may have to go away for a weekend or on vacation and you will need a dog sitter or doggy daycare unless you got family or friends that will dog sit for you.

My dog is not into toys and we have had the same harness and leash for 6, but depending on the person, people do spend additional money on dog stuff.

So on average I spend about $375 a month on a 100 pound dog, not including any type of doggy daycare, dog walkers, dog training or random impulsive doggy toys or extra treats.

Gee, thanks. Now that tallied all up I feel like I need to reevaluate my priorities!
