Be sure you let parents know that you are taking precautions with the pets in terms of not allowing the pets free reign around the children and only allowing supervised interactions. Mention about keeping the yard cleaned up or restricting the dog to their own bathroom/run area not accessed by the kids - anything that eleviates the parents fears of dangers - even very friendly dogs bite when prevoked or feel threatened. There are more and more families with allergies. Often it is the parent and they are concerned their child might have one too or don't want to havea to deal with pet hair coming home on the child and setting off a reaction in the adult.

We had dogs up to 3 years ago and over the years I did lose some kids because of it but those were often the parents that were touchy, afraid of shadows harming their child and in the long run families that don't come because of your pets may be a good thing for your daycare.
