Collar: leather or non-stretch material. Make sure it is "2-fingers" snug and can't come off.
Dog leash Leash: strong clasp and thick leather or double-ply woven for your comfort.

Crate: an invaluable tool, especially at the beginning. Avoid crating a dog for more than 5 hours. Place safe toys inside. Folding crates are also ideal for traveling. They are not essential but can be very useful.
Water and food bowls: use stainless steel or ceramic with no painting in the inside. Plastic can absorb bacteria and smell.
Flea comb: check for fleas, and comb to aid the skin. Good "shedding" control, too.
Brush: brush daily; good for skin and can be better than bathing.
Grooming supplies: get the right tools for your dog if you're going to bathe, clip claws and cut fur yourself. Different coats require different brushes.
Dog bone

Food: gradually change over to the food of your choice. Use a good grade of dog food. Premium dog food can lead to lower vet bills. Dry food is good for teeth and digestion.
Biscuits: avoid those with food coloring. Use to reward good behavior.
Low-fat plain yogurt, grated organic carrots and parsley: good daily diet supplements.
Organic apple cider vinegar: a little added to water bowl daily can help digestion and deter fleas.
Rescue Remedy (available in health food stores): calms when traveling, nervous or injured.
Toys: use safe chew toys, such as non-rawhide-based chew-strips. Soft toys are good for some dogs, but others will pull them apart, so remove if this happens.

Contact your local council for information about fees and requirements for registration in your area. Most councils offer considerable discounts for desexed and microchipped dogs.

Dogs don't come pre-programmed. In your dog's previous life, he may have been encouraged to jump up on people, steal food, or play too rough. Use clear, simple, consistent commands and positive reinforcement. Reward good behavior with treats, hugs and a happy voice. Use corrections sparingly.
