Trust me, once you get to 4 its a piece of cake. But yeah the food and vet bills get up there.I agree. I have three. Not a whole lot more work than one (they typically play and sleep with each other), but it is a lot more expensive.Not much more work honestly - they keep each other company. The only big difference is the vet bills since our second came with some health issues (both of ours were about 4 years old when we got them).
It may depend on breed though. I have pugs, which are a bit less work than some other breeds.

I have 4 ranging from a little #### to a 140lb Great Dane. About 300lbs worth of dogs so yeah food bills are a bit much. Worth every penny.
