Revised AHS/ASV Heartworm Guidance Document For Relocation of Dogs

Transporting and relocating dogs is a common practice for rescue and sheltering organizations.  In many regions of the US pet overpopulation is still an issue, while in others there are not enough adoptable dogs to meet the demand.

Management algorithm from AHS/ASV Guidelines for Minimizing Heartworm Transmission in Relocated Dogs

In their revised guidance document, the American Heartworm Society (AHS) and Association of Shelter Veterinarians (ASV) recommend the following practices to reduce the risk of heartworm transmission associated with dog transportation and relocation.

  1. Test all dogs greater than 6 months of age for microfilariae and heartworm antigen.
  2. If dogs test negative, proceed with relocation.
  3. If dogs test positive (for microfilariae or antigen), reconsider relocation and begin comprehensive treatment in accordance with AHS guidelines for all dogs with heartworm disease.
  4. If dogs test positive and relocation cannot be postponed, management guidelines are outlined for minimizing risk which include treating with a microfilaricide and insecticide prior to relocation. Once heartworm positive dogs have been safely transported, complete treatment in accordance with AHS Guidelines as soon as possible.
