My 19-month-old Labrador x Golden Retriever is great with most commands and has reliable recall, [I]except[/I] when she's sniffing. This is a particular problem at our local dog park after rain, but also at other unpredictable times.
She will often make a beeline to an area from quite some distance away, and once she's sniffing she becomes oblivious to my calls - it's as if she's deaf. If I walk up to her and leash her I can lead her away without any resistance, but if I don't take her far enough away she will run back the second I unleash her.
I worry that one day she'll bolt across a road to sniff something. I really can't seem to get her attention at all when she's like this (not with calling, a ball or treats - even when I'm right up close to her).
What should I do?
