A mixed breed dog is just what it sounds like - a mix of one or more different types of breeds. For the most part, the history of a mixed breed dog’s ancestry is not known, but guesses can be made for the parent breeds based on the dog’s appearance. Tracing a mixed breed’s family tree back any farther than that is a difficult to impossible task.
Medium-sized mixed breed dogs weigh between 21 to 50 lbs. Because dogs inherit characteristics from either or both parents, and in the case of a mixed breed dog the parents may be unknown, it is difficult to predict their temperament. However, if your medium-sized mixed breed dog sports the beard of a terrier, it’s likely he’ll have the spunk and spark for which terriers are known. The color pattern can also be a telltale sign - your white dog with brown and black spots probably has some Beagle in it, and you may hear its characteristic howl from time to time.
Due in part to their “hybrid vigor,” mixed breed dogs tend to be less prone to as many genetic diseases as their full breed cousins, but they can still develop hereditary and congenital conditions, including hip problems such as hip dysplasia; knee problems such as cranial cruciate disease; skin conditions such as atopy and demodicosis; skeletal diseases such as intervertebral disc disease (IVDD); and thyroid diseases such as hypothyroidism.
Thankfully, Petplan pet insurance covers all hereditary and chronic conditions for the life of your pet as standard. Which means if your medium mixed breed inherits a combination of trouble from his parents, you're covered.
