Generally, we don't recommend people should have two dog puppies. Two bitch puppies probably won't fight and are likely to grow up well together. Be careful when introducing a new puppy into an older Skye Terrier's territory. Both older dogs and bitches can be a bit snappy at first, but should learn to get on well enough. With a dog puppy this can lead to fights later, as he seeks to establish his dominance.
Care needs to be exercised .
Introducing a puppy of either sex to an existing bitch is less likely to lead to dominance fights.
