This article is from the Whippet Breed FAQ, written by firstname.lastname@example.org (Nancy Bennett).
Whippets, like other dogs, require a good quality kibble and plenty of
fresh water. Grooming is minimal -- cut their nails regularly, bathe
as needed, and keep them free of parasites. They are not well-adapted
for living in a kennel or as outside dogs. Their coats do not provide
the insulation for them to withstand prolonged periods of exposure to
the cold. Their natural attachment to people makes them happiest when
kept as housepets. They need soft bedding on which to sleep, regular
exercise, and routine veterinary care. The most important thing you
can do to care for your Whippet is to protect him from being hit by a
car, or attacked by aggressive dogs. Whippets generally get the worst
of any dog fight, so "invisible" fences are not recommended. Protect
your Whippet with a safely fenced yard, or by walking him on leash.
Puppies can be chewers, so crating is recommended when you are not
able to supervise their activities. Obedience training will make
your Whippet a better canine citizen.
