This is a relatively new development, but it is quite annoying. When anyone comes home, Brody wants to sniff them over in a quite intrusive way. This isn't your classic crotch sniffing, it's all up and down their legs, feet, and even jackets when they remove them. He is particularly interested in my one daughter who is the least fond of Brody to begin with, and it hasn't endeared him to her one bit. The few suggestions I could find online just said things like "let him sniff more on walks", or "toss his kibble into the grass" to help him work out his need to sniff. He does sniff a fair bit on walks, and I have been stopping at grassy patches to let him investigate. The kibble in the grass is not doable as it is quite wet here, and I don't have time to stand around and wait for him to eat his food outside anyway. Due to situations with neighbor dogs, I never let Brody stay outside unsupervised. I don't think this is an obsessive behavior, but it's something I would like to nip in the bud. Any ideas?
