Introducing A New Dog Into A Family With A Jack Russell
Jack Russells are a tenacious breed that sometimes has problems getting along with other animal, especially new animals that are coming into the household for the first time. The Jack's person might be lucky, especially if the Jack is a female. This luck would mean that the female would take on a mother's role and help the puppy acclimatize into the family.
Jack Russells are very aggressive to outside animals and a training method that could be used to help them accept the new dog is to get them used to other dogs outside your family. You might want to take you Jack to a dog park and let them get used to new dogs.
Remember that a dog has to get used to another dog in their own way which means that there might be a little aggression at first. Keep them on a leash so you can pull your dog away if the aggression becomes dangerous. The dogs have to show dominance. This may be through being a little snippy at first but learn their behavior so you can get them through the initial meeting.
The more dogs that your Jack meets the less intimidating your aggressive dog will be. You and your Jack Russell Terrier will learn together how to incorporate new dog encounters into your life. When you bring that new puppy home for the first time, your Jack will be very curious. The puppy will not know the behavior of an older dog and will think the Jack wants to play. This is a crucial time for both the puppy and the Jack. The Jack Russell will show some aggression the puppy will not understand, but be prepared to let them meet briefly for a few seconds if it is real aggressive.
The Jack will slowly accept either as a puppy in which they will protect it or the puppy will become a nuisance and the Jack Russell will ignore and distant itself from.
