I dunno what the hell mr. unregistered is talking about , but the only dog you have is
Dogmeat.
You get him in the scrapyard , he/she fights off 5 or 6 raiders by him/herself and then
will approach you. You can then have him/her join you if you select the appropriate speech
patterns.
His/her gender has always been questioned (same with fawkes) since different sources will
sometimes refer to dogmeat as a female. Which stirred a lot of controversy on this issue.
On top of that , with the new perks available with the add-ons (soon to be released for
PS3) , there is a perk that mentions dogmeat's "litter". And as you well know males cannot
carry litters. On the other hand if dogmeat is in fact female then how would she get
"knocked up" in the first place. By those Vicious dogs ?
This argument can and usually does carry on quite a bit. However , official spokespeople
have claimed that dogmeat (and fawkes for that matter) is in fact male. Hoping to put the
argument to rest.
