The males range from about 40 to 55 give or take. And........no they are not hard as nails at all. Most folks breeding them today have confused good handling and intelligent with lazy and cowardly. Like I always say, "dont believe they hype".
They are just mongrel types of any sort. Cur dog means so many different things it's hard to explain. Could be an old farm collie or farm bulldog bred to a hound type or like you said a terrier type to a hound. Nowadays they have them registered and shit though so who knows what they are. A good one is neat to have around though.
Get yourself a bullx kid. Best "pets" I've ever seen in my life have been some of these yard bred bulldogs. That's about 99% sure what kinda bullcross you will be able to get your hands on anyhow so I think it'd be a good choice for ya. It's not like you are gonna be able to jump right into some 8th generation type bullcross dogs anyhow that are the real mccoy so I say go for it. Be a smart little tool and handy to have around and be your buddy.
Another thing, how did this get turned into a pissin match between yall and us. There is no ill feelings on our sides towards any of yall so I dont get it.
