Generally, Cesky terriers are very healthy dogs and given a good, balanced diet, plenty of exercise and mental stimulation, should be no more prone to ill-health than any other dog. Cesky terriers can suffer from an ailment called Scotty Cramp. Breeders are very aware of this problem, but as yet there is no accurate test that can be carried out to detect potential carriers. Fortunately there have only been a very few cases in this country, as breeders try not to breed from those lines they think may carry this ailment. Always seek the advice of your vet or the breeder if you are worried.
Cesky terriers love company and get on very well with each other, and other breeds.
