I agree. Beagles can be very hard to train. Once they start sniffing they can just follow their nose. Great dogs but too sniffy.
I have a mini Daschund and LOVE him! He is the best dog ever. My wife is really good at training him. He is very well mannered. I would have him over a beagle anyday. Thats just my personal prefference though.
I do agree that training 2 at a time is almost impossible unless you are a pro. One dog love you more than 2 anyway. 2 have each other.
