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 Cornish Rex (2.5–4.5 kg, 11–15 years) and the Sphynx (3.5–5 kg, 8–14 years) sit in different — or sometimes overlapping — corners of dog ownership. Here's how they really compare for an everyday Irish or UK family.
Energy levels are well-matched between the Cornish Rex and Sphynx — both need similar daily exercise.
Grooming is where these breeds really diverge: the Sphynx 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.
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.

SphynxEnergetic, mischievous, intensely social, attention-seeking. Sphynx cats often follow their humans like dogs and can be jealous of a single owner's attention.
Very active. Need play, climbing, mental enrichment. Many do well with another cat for company.
Surprisingly high. Weekly bathing is essential — skin oils that fur normally absorbs build up on the skin. Wipe ears weekly. Sphynx feel cold easily and may need sweaters in winter.
Hypertrophic cardiomyopathy (HCM — DNA test). Skin issues. Heat sensitivity (sunburn risk). Dental disease.
