My Dog Hates Cats

Besides having the ability to socialize with humans and other animals, dogs are natural predators. 

Seemingly, your dog hates cats because of the predator genetic formation derived from the wolf family. However, some puppies have been taught how to manage this natural canine instinct and socialize with cats well.

Why Does Your Dog Hate Cats?

Neglect or lack of attention for your puppy can trigger anti-social behavior in your dog. The majority of pet owners will confess to having had a dog cat chase situation at least once. Sometimes, dogs that are trained to socialize with other pets can suddenly develop an aversion for cats.

Dogs tend to get mischievous when left to their own will. This freedom can trigger the natural predator instinct to chase and kill other smaller animals such as cats. 

In the wild, dogs and cats are almost sworn competitors. It is no wonder that this behavior will once in a while show up in your domesticated puppy and cat.

Is It Play or Hate, When Dogs Chase Cats?

Canines naturally love to chase moving objects, especially smaller ones like cats. The hunting instincts passed down on your rover from the wolf ancestors come to play once in a while. 

Cats are playful and will often chase crawling and flying insects. A fast-moving kitty can trigger the predator instinct in your dog and cause it to initiate a chase. 

Like humans, animals also have a way of communication. Wagging and swishing tails portray different messages in dogs and cats. Your dog interprets this as playfulness while a cat shows distress. This misinterpretation of messages causes misunderstandings between dogs and cats.
