Rat Terriers are typically active, energetic dogs. This can mean that even well-fed dogs burn so many calories each day they still look thin and undernourished. For these Rat Terriers, there are several ways you can approach helping them to gain weight. Choose the method that works best for you and your dog, and give it time to take effect before you try to determine whether you are on the right track or not. If it doesn’t seem to be working, you can always switch to a different method or try using two or more strategies at the same time.
Weight Checks
Rat Terriers are generally lean dogs with slender bodies, so even if they seem a bit thin, they might actually be fine. A good way to check is to look down on them from above, while they are in a standing position. You should be able to see their shape, with a definite narrowing from the ribs to the hips. Their ribs and hip bones should not be obvious or sticking out. Run your hands down the sides of your Rat Terrier. If you can feel the ribs just slightly, but they are not pronounced, your dog is at a good weight. If you can easily feel each rib, the dog is too thin, and if you have trouble finding the ribs, the dog is overweight.
Amounts
To help underweight Rat Terriers gain weight, the easiest strategy to try is to increase the amount of food you give them each day. One way to do this is to add an additional meal to the normal routine, so that you are feeding them three times per day instead of two. Alternatively, you can feed Rat Terriers the same number of meals but increase the amount given at each regular feeding. Adding between-meal treats such as cubes of boiled liver or chicken is another way to increase how much food your Rat Terrier gets.
Free Feeding
Place a dish of good-quality dry dog food where your Rat Terrier can reach it at any time of the day or night. This isn’t a good strategy for puppies, since they need to relieve themselves soon after eating, but it works well for adult dogs that are able to wait to go outside. Allowing dogs to choose when and how much to eat may result in them taking in extra calories, helping thin dogs to gain weight. Only use dry kibble for free feeding, since moist foods of any kind may spoil and possibly make your dog ill.
Considerations
Since Rat Terriers are small, they do best when fed a concentrated food that is rich in protein and other nutrients. Check the ingredients, and if a grain such as corn is listed as the first ingredient, try switching to a food that has a specific type of meat, such as chicken or beef, listed first. Ingredients are listed based on how much is used in the food, so the first ingredient is the largest single component of the food. Grain-based dog foods can be hard for small dogs to digest, whereas protein-based dog foods are highly digestible, so your dog gets the full benefit of the food. If your Rat Terrier still doesn’t fatten up, have your veterinarian check for worms or other health problems.
