I just had a thought that has turned into a concern.

We're going out of town next week and will be boarding her. She will be crated at night, but she'll be in the day care environment during the day. I liked this idea better than being caged the entire time we're gone. She has just turned 11 months old. She has yet to be altered. I plan on doing it, just haven't resolved myself to put her through it yet. When do Yorkie's usually encounter their first heat? Is my concern valid?
