I stud my male out to only females who weigh 1 lb or more than he does. He is 3.5lbs so 4.5 and heavier is about right. Not to mention Tino has a long family history of alot of pups and they tend to run smaller in his pedigree so I wouldnt breed him to a small female in fear that she would have to get a c-section or something going wrong. |
