When a pet is begging for food, it is sometimes hard to resist giving them a little taste of your meal. Dogs aren’t known for being picky about their food, eating the same kibble day after day with relish. However, owners of spoiled pooches want their pets to have the best possible culinary experience, especially for those rare finicky canines. Though pets of all kinds are known to beg, dogs tend to do so most often. There are several human foods that can be given to dogs occasionally.
Now, researchers reporting results from a pilot study in ACS’ Journal of Agricultural and Food Chemistry have identified key aroma compounds in dog food that seem to be the most appealing to canines.
For dogs, palatability depends on a food’s appearance, odor, taste and texture — just as it does for people. Previous studies have suggested that odor is especially important for dogs. Some scientists have identified volatile compounds in dog food, but not much is known about how specific aroma compounds influence how readily the dog eats the food. Maoshen Chen and colleagues wanted to identify the key aroma compounds in six dog foods and correlate the compounds with dogs’ intake of the foods.
In this small study, the researchers began by feeding six adult beagles one of six foods for one hour each and determining how much the dogs ate. The intake of three of the foods was two to four times higher than that of the other three foods. Using mass spectrometry, the researchers found that 12 volatile aroma molecules were correlated, either positively or negatively, with the beagles’ intake of the six foods. Then, the researchers added each aroma compound to an odorless food and gave the beagles a choice between food containing one of the compounds and the odorless food itself.

From these experiments, the team determined that the dogs preferred food containing several compounds including (E)-2-hexenal (which humans associate with an unpleasant, fatty odor), 2-furfurylthiol (a sulfury, roasted, smoky odor) and 4-methyl-5-thiazoleethanol (a meaty odor).
In contrast, the dogs didn’t care for food containing (E)-2-octenal (a slightly different unpleasant, fatty odor).
Although other dog breeds and more subjects should be tested, these results could help dog food manufacturers formulate more palatable chow, the researchers say.
When does a puppy come home? Most people think that puppies only come when you bring them into your home. Puppy breeds are a bit different than other breeds and you have to know what your puppy is capable of since they are still learning. If you have kids in the house or are adopting a puppy from a shelter or rescue, you should also let them know the right place for your puppy to sleep at night, the boundaries that the puppy should not cross, and the things that he or she cannot do. Training your puppy begins as soon as you bring them home, which generally is around 8 weeks of age.
During this stage, the puppy is still learning and each puppy breed has its own quirks and physical characteristics. Puppy breeds such as the Beagle have long, flowing coats while the Dalmatian has shorter, silky hair that is easily brushed. You’ll notice that there are differences with the coloration of each breed as well, and you might even see some puppies that look more like they have a human accent than their other traits. When it comes to puppy training, you need to teach them the difference between good and bad behavior so that they will know what they are getting into while they are growing up. These kinds of lessons can be learned in a variety of ways, and there are books that you can purchase or take home with you that will teach you everything you need to know.
When it comes to puppies, most of them are quite easy to train and can become quite an asset when you get older. However, training dogs can be difficult, especially if you are just starting out with them or if you don’t have much experience in the subject. There are many different ways that you can go about training puppies, and whether you are an experienced trainer or just trying to figure things out on your own, there are some tips and tricks that you should keep in mind before long. Good luck, and happy training!
