Without even addressing any of the other points you brought up...
5 years is too old for a female to be bred for the first time. It would pose severe risks of complications for your girl. At that age, their pelvic structure is 'set' and will not 'adjust' to accomodate a growing litter in her belly.
For that reason alone, I would suggest that breeding her, even once, not even be up for consideration. |
