This one is worth a bit of thought before making a commitment.

Not an easy one. It is said male dogs are location protective and female dogs pack protective. Males can be very territorial. Two male dogs - not a wise move! Females have the pregnancy syndrome but are less likely to wander. They sometimes say two females can be a problem. Our situation, which is a male (entire) and a female (spayed), suits us well. Carla's (the female) situation was a requirement of the Blue Cross Rescue Centre when we got her, so we had little choice in the matter.

As I may wish to use Ralph in the future for breeding - he is "entire".

At the end of the day you have to make your own judgement in accordance with your circumstances. Just think about it beforehand, definitely easier than later when you are committed.
