View profile →Frequently asked questions
Is a Prague Ratter good for apartments?
Yes, it is one of the better toy breeds for flat living. It is tiny, needs only light daily exercise and settles well indoors when its needs are met. It will alarm-bark at sounds, so a little training around the doorbell helps keep the peace with neighbors.
Is a Prague Ratter fragile?
Yes. At 2-4 kg it is easily hurt by a fall, a rough grab or a bigger dog's play. Small children should not carry it, and it is safest supervised around large or boisterous animals. Careful handling is part of owning any toy breed this small.
How much does a Prague Ratter cost in the US?
The breed is uncommon in the US, so expect a limited number of breeders, possible waitlists, and sometimes imports; puppies commonly run roughly $1,500-$3,000. Across a 12-14 year life, routine food, supplies and preventive care typically add $8,000-$14,000 or more, and dental work or knee and heart care can add thousands on top.
Is a Prague Ratter good with children?
It can be, but the match depends on the kids. Calm, older children who understand gentle handling do well; toddlers who grab or drop are a real injury risk to such a small dog. Always supervise interactions between young children and any dog.
