Urr Dog Formula

MURR aims to improve quality and longevity of pets’ lives for a more meaningful connection with their owners. All dog owners want to feed their dog a healthy and tasty food! But what is a healthy food for your dog...well we at Murr would like to remind you that nature knows best!

Urr® dog food is scientifically formulated from choice Icelandic meat and organ meat. Ingredients in our food are specially selected to fulfil the nutritive requirements of your dog without using any additives or preservatives. We only use ingredients passing strict veterinary inspection.

Despite common misconceptions, the dog is classified as a carnivore. Although some people choose to call them omnivores, the anatomy of the digestive system identifies the dog as a carnivore. The primary energy source for omnivores is carbohydrates, but not for the dog. Dogs exhibit some of the metabolic characteristics of both omnivores and strict carnivores but the primary energy source for omnivores is carbohydrates, whereas the primary energy source for dog is protein. Although dogs are less strict in their diets than cats, they still possess metabolic characteristics of strict carnivores. Due to their metabolic characteristics, dog food must be carefully selected for its animal components.

Critical facts about the nutritional and health requirements for dogs:
  • Murr specializes in food for small breed dogs
  • The metabolism of the dog is better suited to deal with carbohydrates than the cat
  • Nutrient requirements of dogs depend on size, breed, and stage of life
  • Murr aims at prolonging the length and quality of life and delaying the onset of geriatric dysfunction and disease states
  • Small dogs are known to have problems with foods containing high proportion of carbohydrates, especially dry foods – The greater use of plant material, the higher is the risk of nutritient difficiencies
  • The Murr solution is a balanced relatively low carbohydrate food containing a high quality component of animal source
  • The animal component ensures nutrient adequacy and the carefully selected carbohydrates provide the right consistency to the food and assist in maintaining gut health
  • Since dogs can to some extent can utilize plant materials, food producers and owners have a tendency to forget that dogs are in fact carnivores
  • Dogs to certain extent have the capability to convert β-carotene to vitamin A, tryptohhan to niacin, Cysteine to taurine, and Linoleate to Arachidonate

The Murr solution to the nutrient needs of the dog
The all-natural raw material, animal organs and tissue contain different amount of vitamins. Therefore, ingredients in the Urr dog food are carefully chosen to meet the vitamin requirements of the dog. Correct combination and treatment of raw material ensures that the dog will not suffer from any vitamin deficiency

Salt content of Urr dog formula
Salt content in Urr foods is about NaCl, sodium chloride or common salt. We do not add any NaCl to our Murr and Urr products. Mineral concentrations in pet foods according to AAFCO are expressed as concentrations of the respective cations and anions. Thus there are requirements to be fullfilled for Na (sodium), K (potassium), Cl (chlorine), I (iodine) etc. NaCl is not measured as such. The minerals in our foods originate in the food ingredients where they occur as natural constituents of the various animal organs and tissues used. If we assumed that all the Na and Cl in Murr and Urr foods would be found as NaCl then the concentration in Murr foods would be about 5 g/kg DM (dry matter) or 1.25 g/ kg feed or 0.125 g/bag of feed. The corresponding concentration for Urr foods would be about 7.5 g/kg DM or 1.88 g/kg feed or 0.188 g/bag of feed. This is, however, absolute maximum as both Na and Cl occur in associations with other mineral ions and are in fact part of the electrolyte pool of the tissues.

Summary of information for Calcite
The ingredient declared as calcite, is produced by Icelandic Sea Minerals of Bíldudalur in a neighbouring fjord to the Murr feed plant. Icelandic Sea Minerals has a joint venture agreement with Celtic Sea Minerals in Ireland. Processing, characteristics and chemical composition of this ingredient, Lithothamnion calcareous marine algae,  is described in a Celtic Sea Minerals brochure.
Murr® pet food, exported to the US, is produced and its contents declared according to AAFCO regulations in the US. AAFCO has accepted Murr® feed labels. On the feed labels the calcareous algae have been declared as calcite. The mineral content of the Lithothamnion calcareous algae is 65% calcite, 23% aragonite and 12% vaterite. As aragonite and vaterite are polymorphs of calcite with the same chemical composition (basically calcium carbonate) it was felt safe to declare the calcareous algae as calcite. Calcite is defined by AAFCO and is a recognized feed ingredient with an international feed number (IFN 6-01-067).
Lithothamnion calcareous algae are marketed worldwide under various trade names both for animal and human consumption. Mineral supplements for dairy cows and pigs are e.g. marketed under the name of Acid Buf (and Calmin in the US). Murr® uses the original Lithothamnion calcareous algae which is the material marketed under the trade name Acid Buf. The specification is presented in a Celtic Sea Minerals brochure for Acid Buf and a certificate from Icelandic Sea Minerals.
It should be mentioned that another Lithothamnion calcareous algae product, Aquamin F, is marketed in the US for human food application. This product has been approved by FDA and has a GRAS status.
