The American Pit Bull Terrier is a muscular dog with a loving and affectionate temperament. However, these dogs have a fighting spirit and may choose to chase cats and squirrels around your yard and home. Early socialization can help get your dog used to living with cats, but they are still likely to chase them even if they don’t intend to hurt them.

2. Scottish Deerhound

  • Dignified

The Scottish Deerhound is a hunting dog that owners often use to hunt deer. Unsurprisingly, these dogs have strong gaming instincts and will likely chase after cats and other small animals even if they don’t intend to hurt them. Early socialization can help reduce the risk of injury, but your cat is unlikely to enjoy being chased.

3. Greyhound

  • Intelligent
  • Athletic
  • Even-tempered

The Greyhound is an extremely fast hunting dog. Since it enjoys the hunt, it is likely to chase your cats, and its size and speed give it an advantage. A Greyhound could be dangerous to have around cats and especially kittens if you weren’t able to socialize it as a puppy properly.

4. Samoyed

Bedlington Terriers are an alert breed, which makes them excellent watchdogs. Unfortunately, this sharp eye over their domain rarely allows intruders like cats to roam free. They will usually chase these animals away even if they have no desire to injure them. This breed will also frequently bark and become aggressive toward other dogs of the same sex.

6. Weimaraner

The Weimaraner is another large and slender hunting dog. It’s extremely fast and has an instinct to hunt small animals. It will often chase squirrels and rabbits in your yard and will have an impressive number of successes. It will also likely chase your cat, though proper socialization when it’s young can minimize this risk.

7. Beagle

  • Intelligent
  • Amiable
  • Determined

A former hunting dog, the Beagle is a small yet determined breed that may not be as fast as the Greyhound or the Weimaraner, but it can fit in much smaller places, and your cat will have a difficult time finding a hiding place. Once the Beagle has the cat trapped, it’s likely to keep it there and bark until someone comes to see it. This entrapment can put a lot of stress on a cat and send it into permanent hiding.

8. Shih Tzu

The Shih Tzu is another small dog breed that can easily fit into many of the cats hiding places, causing it to be a larger threat than you might think. However, unlike the breeds we looked at so far, the motivating factor for aggression is jealousy. Shih Tzu dogs like a lot of attention and will not be happy about you petting a cat. It will likely try to chase it away as a result.

9. Schnauzer

Fortunately, the rabbits and squirrels tend to get away, but it can add a lot of stress to a house cat. Early socialization can eliminate aggression between pets, but the Schnauzer will likely always chase yard animals.

10. Irish Wolfhound
