Should you feed your dog treats or biscuits, is one of the most repeated question that dog walkers are posed. As always there is no simple answer. Dog biscuits are very useful for dog training reasons, we all need rewards for good actions. The contrary of no biscuit is clearly punishment.
Feeding a dog treat is great for both of you, sharing a moment and happiness is great for the two of you. So are all dog treats good for your dog? Commercial dog treats are OK, but have a look at the nutritional information, various, chiefly the moist biscuits sometimes have some unpleasant, but legal / FDA ingredients. I prefer to give a dog, identical ingredients I find in my kitchen that I use for my family and children. You choose what goes in and it can be of the quality and cost that fits you. People who favor organic or local ingredients now have a solution for their pooch. There are even vegan and vegetarian recipes, but for these often have protein sources such as peanut butter.
Obesity in dogs is a mounting problem, very similar to the human world and is routed in the same causes. Not enough exercise and too much easily eaten processed food. If you are finding it difficult to find sufficient time for walking your dog, it may be worthwhile using a professional dog walker. Dog treats as part of a balanced diet and lifestyle is part of good dog care.
The standard ingredients you can use are those that are common to your kitchen. Flour is the mainstay of the recipe, all types can be cooked with and if you do not have wholemeal flour, the recipes are often robust enough to take a mix or be replaced by a different flour. Using wholemeal flour really makes a healthy base to the biscuit, which can be strengthened with wheat germ, bran or oat meal. Eggs are also often used.
Baking your own dog treats, like any cooking of goods is very pleasing, but only make enough for your dog, so do it when you are cooking something else. Small amounts. only enough so they stay fresh. They are best for the first couple of days, but in a tight air sealed container, will last for a week. If you do not have the time, you can freeze a large amount, in small bags, the amount for a few days at a time. Margarine is frequently used, but other forms of fat or oil can be used. Sometimes the dog treat will be raised with yeast.
The flavour for the biscuit is either added though meat or meat stock, sometimes with the use of cheese. Salt is dangerous, as for us, do not use too much in the recipe.
[One of baking your own, is that you can vary the treat and see if your pooch prefers it. Often the best modifications, and most practical are when you change something in the recipe, because you do not have that ingredient in the home! 
A lot of dog biscuit recipes are simple, so are wonderful activities to do with the kids. They like hand forming the dog biscuits. They  use all the range of metal or plastic cutters you may have! Please supervise the children making the dog biscuits.
Making the dog biscuits yourself allow you to control the ingredients, particularly if your dog has any ingredient allergies. There are numerous great tasting dog treat recipes.
So enjoy making and giving your special dog treats.
