Hi Christina

My first question would be what breed was the dog she tied with?  The complications could be detrimental even fatal to a Chi.  Not to mention the inherent defects that could be past to the pups coming from a sire.

62 is gestation, you can do x-rays after day 50 when the bones will calcify.
