28. Cavalier King Charles Spaniel
The Cavalier King Charles Spaniel is another old breed with a history of nobility. They have an air about them that exudes authority and being an attention-getter… and they would be right. They’re affectionate and easy-going, making them a great pet to have around children. This need for attention causes them to have extrema separation anxiety, so steps need to be taken to curtail this. They can also be a little difficult to house train, so you’ll have to exercise patience in this area… as well as protect your floors.
