After our recent post about calculating your pet’s daily calorific requirement by working out his resting energy requirement, then applying it to a table of variables; we received a number of queries from maths-shy owners who weren’t confident enough to put our collection of facts and figures to use. Here at the Dog Health blog, we understand information is useless unless you understand how to use it, so here’s some clarification.
Let’s suppose you own a very active, 20 kg Border Collie and you want to use our strategy to make sure you’re feeding him the right amount of food. First, you should work out his resting energy requirement, or RER. To do this, multiply his body weight (20kg) by 30 and then add 70:
RER = (body weight x 30) + 70
= (20 x 30) + 70
= (600) + 70
= 670 calories
Easy! Now, look at the table in RER post. Although he is not doing lots of work (like he would on a farm), if your dog is very active and spends lots of time running around outside on walks, chasing balls and fetching sticks – you’re probably going to need to feed him a bit more. The table says the amount of calories an adult dog doing light amounts of work needs is 2.0 x his RER. His RER was 670 calories, so you need to multiple that by 2.0.
Daily calorific requirement = RER x 20
= 670 x 2.0
= 1340 calories
Simple! Your dog needs about 1340 calories every day to keep him healthy and happy! Of course, every dog is unique – if he starts getting a bit fat or thin, change his diet a bit to compensate! Hopefully this has helped
