Questions people ask
Is a Sealyham Terrier good with kids?
Generally yes. Sealyham Terriers are usually good with children when raised with them and given their own quiet space.
Is a Sealyham Terrier good with cats?
It can work, with management. Introduce them gradually, feed them apart, and make sure the cat has vertical space the dog cannot reach. Plan to manage it rather than assume it.
How much exercise does a Sealyham Terrier need?
A real walk every day, around 30–60 minutes.
Can a Sealyham Terrier handle hot weather?
About average — use normal hot-day sense.
