Swedish Animal Welfare Regulations
Section 13 of Sweden’s regulations on keeping dogs and cats states that, “dogs and cats may not be kept in cages” unless they’re used for transport, hunting, or a competition or show.
Even then, pet owners are required to let their dogs out of their crates at least every two to three hours.
I am sure you can find a lot of good info here on crating. Apart from that: why use a crate? Our 2 B's can sleep wherevere they want; they don't destroy anything. Sometimes they stay on the couch, sometimes they join me in bed. I'm from the Netherlands and I learned through other basenji-groups that crating is illegal in a country like Sweden, unless for transportation. All the best!
What worked for us while training was a harness with front attachment: if the dog starts pulling, it pulls itself around towards you, so you can get his attention and start over. Furthermore, we found out over time that when we walk the dogs, it's THEIR walk and they can sniff around as they like, on a long leash. When we need to go somewhere, we take the leash short, and by now they understand that this means walking nicely next to us. Maybe not by the book, but it works for all of us.
If you can, try fresh food: raw meat, soft bones, cooked vegetables, eggs, chewing stuff like tendons, cartilage. Our Lela was a muncher with kibble but when we changed to raw, she became a little wolf, really into food. And despite what vets say, I hold fresh food healthier than kibble.
Some good advice already here, and remember that you have to figure out what works for YOUR dog and YOURSELF - part of the magic of having a dog I guess (or kids). Our first pup, when in puberty could bite hard, too. We found that sound or verbal commands did not work (for dog and ourselves). We took to body language, standing firm (Yang in Chinese terms, putting some energy pressure, but not too much), silently, turned towards the dog, and turning with her movements, so she knew we were actively involved in the scene. As soon as she got it and stopped, we would go soft (Yin) again and turn away to take away the pressure. It took patience and practice, but we learned a lot about how these non-verbal interactions work and what makes our miss Lela tick. We still prefer - whenever possible - body language over verbal commands.
