Our dog is 1 1/2 years old and is houseborken. Recently we moved to a house in the south for the winter. She is peeing on the ceramic tile floor almost every time we leave her in the house (just for 1 - 3 hours). I don't know what to make of this. Is it because it is a strange house? Or, could she have a below-normal ability to hold pee? I wonder because until now she goes to play groups during the day and spends a lot of time outside so we have never really tested her ability to last any time without peeing. Normally, she pretty much gets to go out whenever she wants (and will ask to be let out when she needs to).

Her only other accident in the last year was when we were visiting a relative and we left her while we went out to dinner. Is it being in a strange house? Or is it that she is upset or angry?

I am perplexed.

She may smell old pee. She may be trying to make the house her own by marking her territory. She may be doing it because she misses you.
