Coprophagia (eating of excrement) is a natural phenomenon in animals. It often indicates boredom or a habit adopted by the animal at a young age. It may also indicate that your pet is not properly digesting and absorbing all the nutrients in his food.

To resolve this problem, we recommend disposing of your pet’s stools as soon as they are produced, playing with your pet more and feeding it a balanced and easily digested food. You can also add a product to your pet's food that will give the stools an unpleasant taste (available at pet stores).

Eating stool is not dangerous for your pet, unless it contains parasites. However, it may also be a sign that your pet needs to spend more quality time with you, or that he needs better quality nutrition.

The presence of beet pulp in pet food does not make a dog's skin or fur change colour. Normally, your pet's diet is not the cause of any changes in its fur colour.
When the fur of a white-haired animal develops a reddish tinge, it is usually with the result of a copper deficiency and is considered a symptom of anemia, -- a rare occurrence in dogs. Other symptoms include skin lesions and dull, tired-looking fur. Very few studies have been conducted on this condition because very few dogs show all of the symptoms.

Generally speaking, reddening of the fur is usually the result of several things:

1. Dietary factors
A lack of certain nutrients can affect hair pigmentation. The addition of free available tyrosine ( an amino acid) can prevent the coat reddening and optimize hair pigmentation in dark coat breeds. This could be beneficial even for diets that have a level of tyrosine above current recommendations.

2. Foreign substance on the fur
Foreign substances on the fur are the most common reason a dog’s fur reddens. For example, shampoos or creams often contain insecticides that can affect the colour of fur. Exposure to the sun can also make your pet's fur take on a reddish hue. However, if your dog has black fur, there may be another reason. The tips of older hairs in a dog's coat that have not been shed early enough will often take on a reddish tinge. Once the dog sheds, the colour of the fur returns to normal.

3. Porphyrin
Another frequent cause of red fur is porphyrin, a substance present in dog's saliva and tears. Reddening of the fur around the eyes occurs frequently in small dogs with white fur after exposure to the sun because of the porphyrin in their tears. Also, dogs that suffer from allergies lick themselves repeatedly. This results in porphyrin being deposited on the fur, which can trigger a colour change.
