I have a problem with my bully, he is 11 weeks and everytime we go out on a walk, he is constanly sniffing the floor. He started doing this about a week ago, and he does that inside the house as well. I do give him time to sniff around on our walks but he wont stop when we are actually walking. When we play fetch he will go get the ball and when picks it up, he will drop it and start sniffing around. Any advice please, any info its greatly appreciated.
