We own a Jack Russell, a Lab and a dog that looks like a Lab, but her daddy might have been a traveling man.
Guess what, they act like Weimeraners.
Jacks. Damn dogs from hell. If you have time to spend with them (A LOT) they are happy. If not, you are not happy. And you better have at least 6 feet of fence to keep the little bastards from jumping over. Needless to say, he went to live with my uncle in the country. One damn happy dog now. He chases anything that moves. You just can't walk in the yard without falling into a 3 foot hole. Diggy little bastard.
My choc. lab that I named Aubie, years ago, was the best dog I ever owned. EVER. But alas, I let him keep his nuggets and he escaped from the yard looking for SOME and got hit by a car. I haven't been that close to a dog since.
Had a Golden. Nice dog. Just never would calm down. My son at 6 years old learned how to lure her into her pen and then lock the door. She played way too rough. And she was 3 yrs old.
So if you have all 3 of those, you must be saving up for new furniture.
