Many of the factors that can disqualify a dog from Heartworm treatment at DAS – such as advanced symptoms or high heart rates – are resolved when they enter a lower stress environment, such as their adoptive home. That’s why DAS does not rule any dog out until they have undergone a post-adoption evaluation by our veterinary team.    Dogs over the age of 7, those suffering from additional medical conditions, or those showing severe symptoms such as coughing, wheezing, and lethargy (particularly in combination with high positive Heartworm tests), are at an increased risk of complications and are more likely to be deemed untreatable in our facility. However, in some cases, our veterinary team is able to utilize different treatment protocols that  cure the dog over a longer time period.    *It is rare for DAS to be unable to offer some type of Heartworm treatment for Heartworm positive dogs; however, if a dog is deemed ineligible by our veterinary team, the dog’s adopter will need to work with their private veterinarian to secure care.
