Side-by-side comparison of two popular breeds — temperament, exercise, grooming, lifespan and common health issues. Use it to decide which breed fits your home.
The Devon Rex (2.5–4.5 kg, 9–15 years) and the Selkirk Rex (4–7 kg, 14–17 years) sit in different — or sometimes overlapping — corners of dog ownership. Here's how they really compare for an everyday Irish or UK family.
Devon Rex is the significantly higher-energy dog of the two. If you can't commit to 60+ minutes of active exercise daily plus mental stimulation, the Selkirk Rex is the lower-friction choice.
Grooming is where these breeds really diverge: the Selkirk Rex needs significantly more brushing, washing and coat care. Factor in €30–€80 every 6–8 weeks for a professional groomer if you don't do it yourself.
For allergy sufferers, the Devon Rex is the lower-shed, more hypoallergenic option.
Insurance premiums for breeds with brachycephalic, joint or cancer predispositions run 20–40% above average — check before you commit. We have a free quote calculator here.
