Duration Of pregnancy for your Mastino Napoletano Neapolitan mastiff
Duration of Pregnancy of your Mastino Napoletano
In every text book, the duration of pregnancy for the dog is given as 63 days. This period does, however, vary considerably both for an entire breed, and also for one and the same bitch from litter to litter. Personally most breeders and myself have found most Neapolitan Mastiff Bitches give birth and whelp usually in between day 60 and 61. This is an average time scale.
