Heartworm Positive Dogs Crowd Shelters Awaiting Potential Adopters

SAN MARCOS, Texas -- While mosquito bites may be a nuisance to us, one bite could potentially be a death sentence for dogs if they become infected with heartworms and go untreated.

  • More dogs get heartworms in spring, summer
  • Higher abundance of mosquitoes
  • Treatment costs a lot of money

The spring and summer months in Texas bring a higher intake of heartworm-positive dogs to area shelters due to the amount of mosquitoes transmitting the disease.
