My pup, about a year old, walks well on leash generally. However, when she sees a squirrel she has a little ritual she religiously observes: 1) staring, eyes glazed; 2) sitting/plopping down; 3) lunging at the squirrel. Since I live in a city and walk her around in parks, we encounter squirrels every. day. If I block her sight of the squirrel with my body she'll just weave around me; if I try to redirect her, she'll sit down; once I do get her walking again, she lunges at the squirrel. I'm able to distract her by waving treats in her face 50% of the time. When squirrels are not involved, her recall is good on and off leash -- and she's extremely responsive to my voice/food. In the end, I usually just pick her up and carry her for a few seconds before setting her down again; this works because she's too distracted by being in the air. Any tips of how to get her attention back without picking her up or pulling her in the presence of a squirrel? She's nearly 40 lbs... Thank you!
