I just wanted to chime in on this and bring up a point someone else mentioned. The low cost vaccination clinics are an excellent way to save money. In my area, if you do annual boosters its $35, rabies is $9, if you buy a 12 month supply of heart worm meds they give you a free heartworm blood test and to top it off they always have tons of coupons in the mail.
My pup got a free rabies shot thanks to the coupon and just last weekend I bought a year supply of Interceptor for $20--regularly $42 less a $15 coupon found in the "junk" mail, less a $7 mail in rebate.

I have 3 dogs so it really makes sense to cut costs in areas like this where you are getting the same service as you would from your vet but at a MUCH lower price and keep those extra savings for annual checkups, blood-work and preventative care from your primary vet.
However, I can still totally sympathize about the vet bills, 2 months ago my pup had to have 4 puppy k9 teeth extracted (2 were loose) and my vet bill was $627 and that didnt involve a cleaning--can you say OUCH!!
