Depending on their physical condition it may be advisable to wait until the spay incision is healed. However your vet, who knows your dogs, should discuss this with you. If they are otherwise healthy and happy, then you will not have to wait long with treatment. Here is a lot of information for you: https://www.heartwormsociety.org/
