Hello Jane - Thank you - we have been using a basket muzzle but are not sure whether it is better to keep it on her for the entire walk (because she meets other dogs and is then at a disadvantage and she already lacks confidence in that direction which is the other issue I submitted at the same time as the scavenging issue) or put it on and take it off at intervals during the walk. She is never short of food and is, in fact, inclined to overweight if she gets too much which makes me reluctant to free feed her. We have also tried the firm low-toned 'no' when she approaches faeces and rewarded her with liver bits or chopped frankfurters when she leaves it but the problem, though less, continues to be a problem. Must we reconcile ourselves to living with it for the rest of her life?
Jane, thank you - this has been very helpful even though I'm thinking that I may very well end up seeing a behaviorist to help with this in person. The trouble is that, sadly, Jessie was often starved during her first years before she came to us and she often had to scavent in order to survive. I guess that experience will always stay in her memory.
I am grateful for your patience with this answer and wish you lived near us! Thank you.
