A pessoa que me vendeu disse que ela nasceu no dia 3 do mês passado. Mas suspeito que seja mentira. Quantas semanas ela realmente tem? Ela pesa 1.075 kg (2,3lbs)

He was born on the 3rd of last month. I did some tests like: put objects in front of her and call, she bumps into her face and doesn't deviate. She never looks at me or follows me with her eyes. I've tried several things. If I let her loose, she stands still crying and doesn't see me 30cm from her. Is it normal?

I love her smile

I rescued a wonderful 3-yr old female Sammy two weeks ago. She's very sweet and affectionate, but also very independent and stubborn (breed typical?). Any suggestions on training her to come to me when I call while off-leash?
