Chugs are quite social little dogs, especially if they have been well socialised from an early enough stage in their lives and therefore they generally get on well with other dogs. However, because of their small size, care must be taken when they meet any dogs just in case playtime gets too boisterous which could end up injuring them. It would be a mistake to trust a Chug around any small animals and pets although if they have grown up with a family cat in the home, they generally get on well together. This is not to say a Chug would not chase the neighbour’s cat if they ever get the chance to.
