Thank you Shark88. It's been 5 weeks now since we lost our amazing girl. Not a day has gone by that I haven't cried at least once during the day. I'll forever feel that had I been more educated on her condition, had I known what to be aware of - the signs and symptoms, I could have reacted sooner. There were signs days/weeks earlier - had I only known what I know now. If I would have recognized her struggle, she would still be with us. At the very least, I would have done everything within my power to care for her. She relied on us to make the best decisions, that was our only job. I can still see her little face looking at me as I walked out the door. I came home from work, I rushed around to leave again and that was that. She likely had been struggling to breath all day and finally, I arrive home - only to leave her again. I plan to talk with my vet, this or next week. I have a list of questions and my hope is that the next owner who has a pet with the same condition will be more educated than I was. That the next owner will be given a prognosis and will be told what to watch for. As far as the new addition? It's almost unbearable coming home every day to the lack of energy in the house. Our older two girls are the loves of our life - they require a lot of love, which we have plenty to give. I've been online every night looking at rescue sights - it's not as easy as I thought it would be to find another rescue female shih-tzu. I've emailed about a few & have had a few conversations. I've expanded my search and I'm also now looking at puppies.
