Approximately 75 years have lapsed since the problems resulting from vitamin deficiency were first noted to be present in dogs. Until this time it was widely assumed that these animals were able to obtain all of the nutrients they required from almost any type of diet available. What is A vitamin deficiency?Deficiency problems caused by a lack of Vitamin A were actually among the first to be studied in the canine species. It was discovered that when dogs did not receive adequate levels of this vitamin they would exhibit any one (or more) of these major health problems:
Vitamin A is not very heat resistant. If food are heated up to 125 celcius for a longer period this will damage the A vitamin. Of course other vitamin and mineral deficiencies can create problems for dogs. Thiamine deficiency creates neurological problems and brain abnormalities and if not corrected a chronic lack of thiamine can lead to heart and circulatory problems.There are statistics that clearly show long term thiamine deficiencies are capable of killing a dog. Without adequate Vitamin E dogs can display evidence of reproductive abnormalities, degeneration of the retinas in their eyes and skeletal/muscular problems.
