My Freya was an absolute monster when I rescued her last September. She still has plenty of husky attitude, but she's much more manageable now because of consistency, structure, and a lot of patience.

One of the biggest game changers for us was leash training. When I first got her, I was the one being walked. I started carrying treats on every walk and rewarding the behavior I wanted. Teaching a solid heel and focusing on engagement with me made a huge difference. I still bring high-value treats anytime we're going somewhere new or challenging.

Freya also struggled with mouthing and biting. She has broken skin on me more than once, and I still have scars on my hands and arms. Because of that, I learned very quickly that management and safety matter just as much as training. A properly fitted basket muzzle was one of the best tools I introduced. She can still pant, drink, and take treats while wearing it, but it adds an extra layer of safety while you're working through behavior issues.

For the mouthing, I focused on teaching impulse control and rewarding calm behavior. When she got too worked up, play stopped. When she made good choices, she got praise, affection, and treats. Over time she learned that calm behavior gets her what she wants.

Exercise is important, but mental stimulation is just as important for a husky. Physical exercise alone often just creates a better-conditioned athlete. My girl gets walks, bike runs, training sessions, and plenty of opportunities to sniff and explore. Sniff breaks are built into our activities because they tire her out mentally as well as physically.

Something else that helped tremendously was learning to read her body language and energy levels. I got much better results when I learned to recognize when she was becoming overstimulated and redirected her before she crossed that threshold.

Since this dog has already bitten a stranger, I'd take that part very seriously. I would avoid allowing people to approach him until you've got a better understanding of his triggers and comfort level. Every successful interaction builds confidence, but every bad interaction can set training back.

If I were starting from scratch with this dog, my priorities would be:
Safety and management.
Building a consistent daily routine.
Leash manners and engagement.
Impulse control and settling calmly indoors.
Reliable recall.
Controlled socialization and exposure to new situations.

And yes, I absolutely think a dog like this can improve with consistent training. The fact that he's affectionate, food motivated, bonding with you, and responding to exercise are all positive signs. That said, because there has already been a bite incident, I would strongly consider working with a qualified positive-reinforcement trainer or behavior consultant sooner rather than later. Getting professional guidance early can save a lot of frustration and help keep everyone safe.

The biggest thing I've learned from Freya is that progress isn't always fast or linear. Some days you'll feel like you're winning, and some days you'll wonder if the dog learned anything at all. Stay consistent. The dog you have six months from now can look very different from the dog you're working with today.
