In organic chemistry, ethoxylation is a chemical reaction in which ethylene oxide (C 2 H 4 O) adds to a substrate. It is the most widely practiced alkoxylation, which involves the addition of epoxides to substrates. In the usual application, alcohols and phenols are converted into R(OC 2 H 4) n OH, where n ranges from 1 to 10. Such compounds ...
A dog's brain undergoes many pathological changes during the aging process. Some of these changes can include damage to the DNA (deoxyribonucleic acid), a decrease in the amount of myelin overlay on nerve cells as well as a buildup of protein in the brain which can potentially have toxic effects.

From time of weaning until the puppy reaches 40% of the adult body weight, the optimal energy intake per unit body weight is twice that of an adult dog of the same breed. [7] From 40% to 80% of adult body weight, energy requirements decrease to 1.6 times the adult requirement, and from 80% to the end of growth, this decreases further to 1.2 ...
Dogs get ample correct nutrition from their natural, normal diet; wild and feral dogs can usually get all the nutrients needed from a diet of whole prey and raw meat. In addition, a human diet is not ideal for a dog: the concept of a "balanced" diet for a facultative carnivore like a dog is not the same as in an omnivorous human. Dogs will ...
In England, care to give dogs particular food dates at least from the late eighteenth century, when The Sportsman's dictionary (1785) described the best diet for a dog's health in its article "Dog": A dog is of a very hot nature: he should therefore never be without clean water by him, that he may drink when he is thirsty.
Diet — There are some disagreements regarding the ideal diet. Commonly, senior dogs are fed commercially manufactured senior dog food diets. However, at least two dogs died at 27 years old with non-traditional diets: a Border Collie who was fed a purely vegetarian diet, [14] [15] and a bull terrier cross fed primarily kangaroo and emu meat. [16]
Generally, the diet recommends 80% meat (including some 'meaty' organs such as heart), 10% bone and 10% organs (of which half is liver). Proponents of the whole prey model diet believe dogs and cats are natural carnivores and do not have any nutritional needs besides what is found in meat, bones, and organs.
The kibble need to be large and very dense to promote chewing, as more time spent chewing will aid in the decrease of accumulation of plaque, tartar and calculus. [21] When the kibble is being chewed, the broken pieces rub against the tooth's surface and scrape off the buildup of bacteria that forms the tartar, plaque and calculus. [ 22 ]
