Believe it or not I have much tinier ones time to time. Bugaboo wae just a pound when he was 9wks. I surely dont breed for them but some times they show up. They are a tremendous amount of work and stressful ( to me), worry, worry. It drives me crazy too. But what can you do? You just have to do the best you can for them. Most important is to make sure they eat. Their little tummys can only hold so much. They must be monitored for hypoglycemia. I keep my smaller ones until they are at least 16 wks to rule out any health problems. I also place them in homes without small children,large pets, ect... They are very delicate. Well good luck!
