I'm sorry to hear that. We had 2 chow/labs. Then, we learned that my daughter was allergic & a severe asthmatic. We moved to a place w/ a backyard so that they wouldn't be indoors, but my daughter kept having to be hospitalized (in PICU). We found out that the mere dander in the air was making her sick. Long story short - we moved again and had to put them to sleep. We couldn't find anyone to take them and I don't believe in releasing animals into the wild to get hit by cars, etc..
That was over 1 year ago & I still miss them both. and get sad thinking about it.
