What would you do if your dog needs a veterinarian, and you are unable to pay? This is a concern many dog owners have had to deal with in this economy. There may be resources that can help you in a tight spot, and it is important to not let your dog go without getting necessary medical attention.
For non-emergency assistance like spaying, neutering, and vaccinations you may contact animal welfare groups for low cost and no cost programs. In my area, you can have your animals spayed or neutered for free. From the county Animal Care and Control website, they have a link to fill out an application for low income individuals to get free spaying and neutering. It is all there for the asking.
Emergency situations are more complex, as you may get many no's before you get a yes, but don't give up. The first step, is to attempt negotiation with your veterinarian. Your veterinarian may be able to work out a payment plan, or allow trading work or services that you are able to offer. Your veterinarian may also be able to get the treatment funded by the AAHA helping pets fund. He/she may also know if there is a veterinarian school in your area that may be able to treat your dog to provide student training. Working with animals, he/she may also be aware of local resources in the community that may be of help.
If that fails, contact your local humane society, animal welfare groups and animal shelter. On The IMOM website, here is a listing of many organizations that may be able to help you in this situation as well.
