Okay, so one dog, you would simply take along? I agree two might be a little much there.
I have time now, so I’ll be answering this question for future generations to peruse.
Pros:
* Two dogs will keep each other company. Most of them enjoy having someone who speaks the same language
* Leaving two dogs can feel better than leaving one
* Watching dogs interact with each other is a lot of fun
* When one dies, you will still have another dog to keep you active, which may help
*...and the obvious: Twice the fun.
Cons:
* Two dogs living together may gang up on strange dogs. Siblings even more so.
* Two dogs may decide they do not really need their humans. However, I consider this rare. Or rather, it is rarely the real reason for a less-than-perfect relationship. If it does happen, individual walks often help.
* Two dogs who are inseperable are very inconvenient. When one is in heat, hurt, sick, or simply less active than the other, it can be a pain if separating them is difficult.
* While dogs do not often pick up good habits, they readily adopt other dogs’ bad ideas. Like kids.
* Twice the hassle on walks, if your dogs are not leash-trained
* Twice the money.
I will gladly come and stay with you. May I bring a lovely Labrador? :]
