Please give me the pro's

and cons

of breeding. I put this thread on the general forum b/c I'd like to hear everyone's views on this.
DH and I are debating on if we'd like to breed Phoebe or not. I've read alot about it and still am not sure if I'm up for the work of it or not. The cost, finding a stud, putting her through it, etc. I was going to call today to schedule her spay appt. but for some reason I'm still debating. My mom bred Shih Tzu's when I was growing up, so I know it's A LOT of work. But I just wanted to get everyone's input on what I should do.
Thanks in advance for your help
