Does a dry nose mean that he is sick?

Second day of school was useful. Explained the loose leash walking. can't wait to try it today.

I don't get it!!! He is really good at home, does all tricks, follows me around. once outside, completely ignores me, prefers others :(

Mac is doing good. he can sit, stay, go down and roll over. not bad for 3 weeks and zero experience in training :)

I got a clicker and a clicker training dog. Wow, they are really effective. I managed to get him "down" in 1 day.

Mac went to his first day of school yesterday. it was good but he peed all over the place :)

He just peed in his crate. Very disappointing. But it is my fault I woke up a little late and couldn't walk him.

He is in his crate and doing pretty good. He only whines for a 10 seconds and then settles down... Good boy..

I am still leash training him. He is stubborn but he will get it one day.

This is Mac. He is a lab/hound mix.
