Food - about $200 per month, about $2400 per year
Obedience classes - $325 per year
Toys - about $100 per year
Annual checkups - $15 per dog, $60 total
The occasional emergency vet visit - $200+ per visit

We don't vaccinate, give heartworm, or give flea preventative, so those costs don't apply to us. I will do titer tests so that they can continue to attend obedience classes, but I haven't asked my vet how much that costs.

So all in all, they cost us close to $3000 a year, probably more. We probably buy more than that in toys and I just don't want to admit it
