S.H.
QueenoftheCastle said it all.....they're truly not for little kids! Good with teens, great with adults.
Every single mini doxie I've known has been personality +. They're hard-headed, phenomenally stubborn, exceptionally intelligent....but all that brain power is lost when they want something.
My sister's mini dox comes in my front door, pees on whatever he sees first, & then jumps onto my antique chair & tries to jump behind the fireplace fence....all in an attempt to find my dogs' toys! He is absolutely psychotic when it comes to toys & destroys whatever he can get his teeth on.
He is hormonal, he attempts to be dominate over my 2 80lb dogs. He owns an entire wardrobe & loves dressing up. He has his own life jacket & whines nonstop if he isn't put on the jet ski when it leaves the dock! He barks nonstop at the fish in the lake, in the cage, & when he sees a fishing pole! When we're driving down the street, he barks aggressively at everything he sees.....& yet, he's the first one in the truck! Loves to travel!
I have to say....I truly believe my 2 80lb dogs are much easier to live with than he is! Oh, & as for the roaming on their own....at night, 1 year or older - if you ever reach that milestone! & it seems that they do much better when partnered with another dog....otherwise they destroy everything in sight. Good Luck....
