Double the dog, double the trouble. So, if you can't handle one dog, chances are you will not be able to handle 2 dogs. And when you have 2 dogs that are not bonded to an alpha human, it is dangerous for your kids.
Now, if you have parakeets, it's a different story. Because, bonding with a parakeet is not absolutely necessary. We have 4 parakeets because we couldn't give 1 parakeet enough attention, so they're happy entertaining themselves. And with 4 of them bonded together it is almost impossible to train these guys to come to us and that's just fine. They can do their bird things and not have to worry to behave for us humans.
