Yes my Sissy is the same way..If she gets something in her fur she stop cold while walking..I have to take it out..I think it is funny..
But she loves to walk and she loves the leaves and all that gooie stuff..so we are usally stopping alot...
Now Daisy hates to walk..sometimes I have to carry her or drag her
(not reallly) i pick her up... it takes alot of trys before she finally start going than you can not stop her..
