Falling in love is one of the best experiences, but if a dog or cat doesn't like a new boyfriend or girlfriend, the road to romance can be rocky.
PawNation.com reports that any interruption or change in a pet's routine can feel threatening and lead to fear, anxiety or even aggression in a pet. Even if the animal hasn't met the new person, they will be able to smell their scents and will start to suspect that something is up.
To turn this suspicion into a friendship, the site recommends allowing the dog and the new beau to meet somewhere neutral - like a park. This way the dog won't feel like the new person is invading their home, and it gives the new person a chance to bond with the animal while playing with toys or taking a walk. Since most cats are indoor pets, the first meeting is usually in the home. The site recommends an owner purchase an elevated cat perch to give the feline a sense of comfort during the meet and greet, as the added height may increase its confidence.
VCA Animal Hospitals reports that using positive reinforcement with a pet may also help it cope with the significant other better. Reward your pet with treats when it allows interaction. This will show your pet that the new person is friend, not foe.
