Cami -- I totally agree. My biggest fear with Cairo was that I would lose her to cancer, even though there wasn't a single case of cancer in her ancestral line. When I looked at Suki, that was my first question. The second was heart and hip issues, and of course, testing, testing, testing. Thankfully, she was bred by a woman who loves boxers, has a treasured boxer that she has shown and received champion titles with, and she has bred her twice over four years, in hopes of getting another show quality pooch. Excellent lines, uber responsible....but my fear is still there. No matter how good the breeding. Why ANYONE would choose to breed a boxer in a line that has cancer I'll never understand. It's heart-wrenching to even consider.
RE: getting another puppy. You have to know when it's time. Cairo was my existence for several years, and the only reason I kept going (came from some nasty abuse at home and in marriage). Losing her...well, I don't need to tell you how it felt. You know. She took a piece of me with her.
Suki isn't Cai...not at ALL.

But she has made it a little easier to come home. I've sat on the floor, feeding her, and bawled like a baby because I miss Cai...and little Suki has kissed away my tears. So she has made it easier, and she is, of course, adored for being herself and such a funny little boxer. I look at her and think, God, I'm so in love with this little thing that has a lifespan of 7-10 years...why do I do this to myself? Yet I can't imagine a house without dogs, and boxers are my heart.
You'll know when the right time is. And there'll be a little smoosh face just waiting for your heart.

Best thoughts to you.
