Cavalier King Charles Spaniel
If you are looking for a smaller breed of dog that is super adaptable, look no further than the Cavalier King Charles Spaniel. They generally match their owners’ energy levels, so if you are not as active as others, they will be content with a decently long walk a day followed by all the cuddles on the couch.
If you are the type that loves to go on adventures and hikes, then they would also love to accompany you, but you should keep in mind that they are not as active and hyper as their relatives, the Cocker Spaniels.
They are known to be affectionate and extremely gentle, so if you have a large family and children, they will be a very good fit. They are quite demanding when it comes to being given attention, and they love to receive pets and love, giving back tenfold. This aspect of their personality also makes them easy to train, as they love to please their owners!
The drawback to them is that they are associated with quite a few genetic health issues, so you will have to be careful about where you get your pup from, as some breeders are not respectable. You can also adopt or foster one from a shelter!
