Commercial Dog Food Diets for Your Dog - Could They be the Right Choice?
Prepared dog food has been highly perfected as to taste, smell, longevity, and nutritional balance, usually with the help of renowned veterinarians. Countless healthy dogs have been raised on nothing else. Completion is keen for this market, and you will find a very large and sometimes confusing selection on your grocery shelves.
Canned dog food, which may or may not be a complete diet, is enriched with vitamins and minerals, containing a mix of protein, fat, and bulk in varying proportions. You will need to study the labels to see which one is best suited to your dog's individual needs. All dog foods are not alike, and any deficiencies will show up in your dogs behavior and health.
All canned dog food products are soft and moist. Due to their high water content, (about 77 percent), you may be giving your dog less nourishment than you think. Because of this lack of consistency between brands, and also your own dog's requirements, no one brand or type will absolutely fill all possible needs. In addition to his dog food, you should also give your dog hard biscuits, a raw carrot, an apple, (without the core and seeds), and a bone from time to time, (but only in larger breeds), as small dogs can't tolerate bones in their digestive systems as well due to their smaller size.
Moist burger or patties are the newest invention in dog food. It looks like hamburger, but is actually a complete food, containing less moisture, (about 30 percent), than canned products, and requires no refrigeration, which is convenient. On the other hand, it is soft, which is fine for older dogs and puppies with teething problems, but healthy adults need chewing supplements if this is their only nourishment. And again, you need to read the label as to ingredients, and possible age recommendation.
Dry dog food has also been modernized in a blend of all the necessary canine dietary elements, but of course in varying amount of the ingredients, so you must read the labels. Dry dog foods come in varying sizes to accommodate the size of the dog, small bits for puppies and small breeds, and large chunks for big breeds. With a moisture content of only about 10 percent, you may want to add water milk or gravy to soften. If your dog eats this food dry he will need more water after each meal. Dry food is usually composed of half cereal and half animal products, with added vitamins and minerals, but very little fat due to spoilage; therefore you will need to supplement fat in other ways.
Dog biscuits are sold in various shapes and forms including whole biscuits and kibble, (broken into small pieces). They are a mixture of cereals, bone meal, vitamins, minerals, with the addition of powdered milk, which is used as a binder. A dog biscuit or dry dog food diet definitely needs to be completed by the addition of meat and fat for the average dog. This has become the favorite diet for many breeders who buy in bulk and can very the quantities of dry food, meat, fat, and supplements to meet the individual needs of each animal.
Dry foods and dog biscuits neither sour nor spoil, making them ideal for a self-feeding diet, in which a constant supply of food and water is available. This obviously saves time and money, but can lead to the obesity, especially if exercise is limited. The recommended quantities on the labels are good general yardsticks, but are average requirements and are not a good substitute for your own observation and judgment. You may have to double the amount for an active dog during cold weather or reduce the amount for inactive dogs.
To summarize, commercial dog foods are convenient, and economical especially if you buy in bulk. However, no one dog food, or food type will fulfill all their needs. You will have to work with your dog to see what supplements you may need to add to his diet, such as fat, meat, a carrot, apple, or a bone, along with vitamin supplements that are now available. Ask your veterinarian what they recommend, and use this as a starting point. Proper diet and exercise will mean a happier healthier pet, and fewer behavior problems and trips to the vet.

Dog Training - Discover What Training Is The Best Way And Foundation To Accomplish Many Types Of Dog Trainings
There are many different styles of dog training, and finding the one that works best for you is important for creating a dog that is a talented, loyal and faithful member of the family. All successful methods of dog training work to reinforce the relationship between dog and handler, and the foundation of any successful training program is getting the respect of the dog. Fortunately, dogs are wired by nature to seek out leaders, and to follow the direction of those leaders.
Both leash/collar training and reward training have been around for a very long time, and they have proven their effectiveness over time. The type of training that works best will vary from dog to dog, and from breed to breed. It is important to remember that each breed of dog has its own unique qualities, reinforced by hundreds of years of selective breeding.
The leash and training collar is the most basic piece of equipment used in training a dog. Using the lead and training collar properly is vital to successful dog training. The training collar is designed to apply a specific amount of pressure each time the leash is tightened. The amount of pressure put on the leash controls the amount of pressure placed on the training collar, and the pressure can be adjusted according to how the dog responds.
Of course personalities of individual dogs vary quite a bit, even within established breeds. You, as the owner of the dog, know better than anyone which style of dog training will work best, so it is important to work with the trainer you choose to achieve your goal of a willing, obedient and friendly dog.
Leash and collar training is the best way to accomplish many types of dog training, particularly in situations where the dog must have a high level of reliability. For instance, dogs that have an important job to do, such as rescue dogs, police dogs and guard dogs, generally benefit from leash and collar training.
The first part of training with collar and leash, of course, is to purchase a quality, well made training collar that will fit your dog properly. There are many types of training collars and leashes on the market. The most important thing is to choose one that is sturdy and well made. The last thing you want to do is chase your dog down after he has broken his collar.
The length of the collar should be approximately two inches longer than the circumference of the dog’s neck. It is important to accurately measure the dog’s neck using a measuring tape. In order to get an accurate measurement, you must make sure that the tape is not tight around the dog’s neck.
In a collar and leash based dog training program, first the dog is taught a particular behavior, generally with the leash. After the dog has demonstrated that it understands the command, the leash is then used to correct the dog if it disobeys, or when it makes a mistake. The leash is the main form of controlling and communicating with the dog in leash and collar training.
When using leash and collar training, the dog must be trained to trust the handler and accept his or her directions without question. In order for the dog to be fully trained, the handler must demonstrate the ability to place the dog into a posture or position he or she does not want to take. This does not mean using force, but it does generally require some level of physical manipulation. This manipulation is most easily and safely done using the main tool of leash and collar training – the leash.
The well trained dog is one who will walk at his owner’s side on a loose lead, neither dropping behind nor charging ahead.
The well trained dog will also vary his pace to meet that of his handler. Under no circumstances should the handler be forced to change his or her pace to match that of the dog.
If the dog does begin to charge ahead, it is important to correct the dog promptly by giving a quick tug on the leash. This will give the dog a good reminder that he needs to change his pace. It is important to quickly relieve the pressure as soon as the dog responds. The training collar is designed to relieve pressure as soon as the leash is loosened.
Most dogs will immediately respond to corrections by a good, properly used training collar. If the dog does not respond as directed, it may be necessary to apply greater pressure. This can be especially true of large dogs or those who have preexisting behavior or control problems. If you are still unable to get a response from your dog, it is possible that you are using a training collar that is not large enough for your dog. If you think this may be the case, be sure to ask for expert advice before proceeding.
