A snuggle or peck from your significant other is sure to brighten anyone's day.

However, while you might be on cloud nine with your other half, don't overlook the fact your four-legged friends feeling less joyful about their humans getting cozy with someone new.

It's a common concern for pet owners, prompting discussions on forums such as Reddit seeking guidance on handling canine jealousy. And behaviour expert Annie-Mae Levy has now addressed the issue, providing clarity and advice for navigating the green-eyed-monster in dogs.

"Yes, dogs can feel jealous, and it's more common than you think," Annie-Mae Levy, an accredited dog behaviourist at by nove8, confirmed.

"Research shows they often act out when they sense a rival - whether another or a person. Dogs thrive on attention and routine. If you hug or kiss someone, they may see it as losing access to you and react by squeezing in between or barking," she explained.

For those looking to harmonise their home life with both their pup and partner, Annie-Mae offers three invaluable tips to curb jealousy and foster a bond between your dog and your new beau.

Help your dog feel secure

To alleviate canine envy, Annie-Mae recommends reinforcing your dog's security through steady bonding and routines.

She advises: "Dedicate a set time every day for one-on-one interaction with your dog, like a walk or a play activity. Also, keep a structured schedule for meals, exercise, and relaxation times.

"When your dog knows what to expect each day, they're less likely to feel threatened by new people."

Introduce your dog to new people at a slow pace

Annie-Mae believes gradual exposure can help a dog accept their owner's new partner.

Recommending a course of action, she says: "At first, the new person should sit at a distance while interacting calmly with you. Let your dog watch and process this interaction without forcing a direct engagement.

"Then, gradually allow them to approach at their own pace and reward calm and non-aggressive behaviour with treats."

She adds: "It would also be helpful if you encouraged the new person to offer treats to establish a positive connection. Don't push it right away, though; give your dog more time to adjust."

Put clear boundaries in place

The dog trainer also emphasises the importance of setting clear boundaries through structured training. "Use commands like 'stay', 'sit' or 'go to your bed' to signal when it's time to give you space," says Annie-Mae.

"Practice these commands in calm settings and gradually introduce them during moments when your attention is focused on someone else. Always reward your dog with treats, toys, or praise for obeying commands."
