When a Whippet doesn't like you, it may exhibit behaviors such as inappropriate urination and defecation, being defiant, not wagging its tail, baring its teeth at you, and not allowing you to touch its belongings.

1. Inappropriate Urination and Defecation
Inappropriate urination and defecation is a sign that a dog dislikes its owner. It is a way for them to express their needs and emotions through marking behavior. A dog that does this may feel insecure and discontent, no longer wanting to be cared for or have your attention.
2. Being Defiant
One of the signs that a dog dislikes its owner is when it acts defiantly. This may indicate that it thinks your decisions are unwise and it would rather act on its own. Intelligent dogs can also observe and make wise decisions based on your actions and reactions.
3. Not Wagging Its Tail
Another sign of a dog disliking its owner is not wagging its tail. When a dog doesn't wag its tail at you, it might look at you indifferently, which shows a lack of interest and unwillingness to please you. This could happen because the owner has done something to upset the dog.
4. Baring Teeth
If a dog bares its teeth at you, it's showing dislike, unfriendliness and aversion toward you, suggesting the dog is very disappointed and dissatisfied. This indicates a lack of trust in the owner, and the dog needs more attention and love.
5. Not Letting You Touch Its Belongings
If a dog doesn't let you touch its things, it might believe that its status is higher than yours and not allow you to touch its possessions. It can also happen if the dog is not familiar with you or doesn't trust you. However, this behavior can usually be improved with training.
When Do Dogs Start to Bond With Their Owners?
Dogs generally start recognizing their primary owner at around 3 months old. After bonding, a dog will show a high degree of obedience, respond immediately when called, obey commands, and follow training. They also exhibit protective behavior, rushing to protect their owner from danger, and staying by their side when they are sleeping. Dogs deeply rely on and trust their chosen owner, they will want to be with you all the time and want you to pet them and keep them company. If their owner is not nearby, they will display signs of anxiety and restlessness.
