The beginning of the month is a reminder to dose our dogs with flea and tick medication. Since it is toxic to fleas, ticks, lice, mosquitoes, and cats, we try to find a period of 48 hours where we can limit contact to humans and other animals. Therefore we don't always medicate on the first of the month.
We found a window of time starting yesterday. Limiting contact with others is not that difficult. The hard part is keeping our two canines separated. For two days we ensure that at least one is always in their crate. This morning no one seems to mind the extra crate time because we sequestered them each with their own raw bone.
