Linoleic acid contributes to good skin and coat. Natural foods such as lean meat, egg yolks and some fish oils are good sources of arachidonic acid.

The only way dogs can obtain such fatty acids is through the food they consume. However, they are specifically classified as a polyunsaturated fat (PUFA) and an essential fatty acid because your dog’s body is unable to produce such fatty acids on its own. Omega-3 and omega-6 are both considered fats, which are necessary for energy and a balanced diet. In general, plant leaves and algae are a good source of omega-3 fats while seeds are a good source of omega-6 fats. Plants can also convert omega-6 fatty acids into omega-3 fatty acids and vice a versa, whereas animals lack the ability to do this and they must obtain adequate quantities of both types from what they eat. Animals depend on getting these essential fatty acids through their diet. However, only plants can produce fatty acids in the omega-6 and omega-3 series, which is why these have been called the essential fatty acids, see Figure 1. These saturated fatty acids can have additional carbon atoms added and double bonds formed by means of different enzymes to produce a wide range of different fatty acids. Plants and animals can synthesise many different fatty acids which perform a wide variety of different functions, the simplest fatty acids so formed are saturated fats such as palmitic acid (16:0 where 16 is the number of carbon atoms and 0 is the number of double bonds). And where the first double bond in the chain occurs also affects its properties if it occurs 6 bonds in from the end of the chain it is called omega-6, while if it is 3 bonds in it is called omega-3. The more double bonds there are, the less ‘saturated’, and the more ‘unsaturated’, is the fatty acid. In addition to the number of carbon atoms, the number of double bonds in the chain is also important. The latter are then called long-chained fatty acids and these are the ones that are particularly important for inclusion in membranes. These carbon chains can be only a few carbon atoms long or they can be between 18 and 24 carbon atoms long. Fatty acids come in a variety of forms but all have the common feature of being a chain of carbon atoms. The properties of the membrane formed will depend on the nature of the fatty acids incorporated. These membranes must be semi-permeable, allowing passage through of some molecules while restricting the passage of others. Biological membranes form the walls of all cells, whether simple single-celled algae or complex specialised cells such as nerves, muscle-cells or blood-vessel cells. Possibly the most important is as one of the fundamental components in membranes. However, in addition to simple storage, fatty acids play a vital role in many biological structures and functions. For example, plants store energy for seed development in the form of oil (eg rapeseed oil or soya oil) while mammals store energy in the form of adipose fat or cod in the form of oil in their livers. At the simplest level, fatty acids in the form of oils and fats are a good way to store energy for future use, since weight for weight fats and oils retain more energy than either protein or carbohydrate. Amino acids are used to make proteins while fatty acids perform a whole range of different tasks in both plants and animals. Omega 3 and Omega 6 fatty acids are considered essential for a dog’s health.įatty acids like amino acids are one of the fundamental building blocks of life. Omega fatty acids are unsaturated fatty acids that are essential for dogs but can not be produced by their body and hence, the requirement needs to be fulfilled by diet or Omega supplements.
