Thanks for your interest. I will bring this up with my board. I can't say that we can move big dogs much faster than we can move small dogs except for some breeds like Pyr, Blue Lacy, hounds, anatolians, etc. However, we do not place the dogs as working dogs which limits us even with those breeds. Labradors and lab mixes are practically impossible to place. We do not accept Pits or Pit mixes.
That being said, we are still interested in transporting our small dogs to rescues that have a faster turnover. These dogs would normally be neutered and have rabies shot, canine disease shot and wormer. Our vet costs in our area are minimal compared to big city costs, plus we have a very successful thrift store operation that subsidizes our programs.
