Jack and Jill came from the same home and want to stay together. They are such happy sweet easy dogs. Jill being the older is a bit quieter than Jack and is happy to nap a bit during the day. Jack is always inquisitive and needs to check everything out. You would not believe he is 10 years old. Jill has a grade 3/6 heart murmur but does not require medication. They are both easy to handle, bath and move around. Both dogs are social with other small dogs but they do like their own space. Jack is not a fan of confrontational male Jack Russells. They both have determined natures, typical of their breed and are both fit and agile and jump on couches and chairs with ease. Both have short coats. Jill weighs 4.9kg and Jack is 6.5kg.
