I've already posted this in the Pomeranian section, but on 2nd thoughts it's quite a general question, so I'm 'cut n pasting' it here.... Hello, I'm looking for advice and I'm starting here. My 1st post so, Hello, my name is Simon, I'm from the UK, near Blackpool. I own a female Pomeranian, she's 4 yrs old and no health problems. I do fancy the idea of her having pups and was recently chatting to some people in the park who owned a male Pom. They, similar to myself want to have pups from their male, he's 3yrs old and very small, they told me he'd had heart problems and at one point lost a lot of hair and weight. He was looking a lot better and had regained all his hair, but he's still a very small Pom, half the size of my girl. Any way, my question is, is it advisable to breed from a male 'runt'? I'm clueless as to whether the 'runtiness' is genetic or it's the pup that didn't feed or got push out by the other pups, but knowing that Pom's have small litters I can't see that being an issue. The fact the male has had heart issues worries me slightly. Thanks in advance for any sensible advice.
