Dogs need to be walked daily, with time spent safely off the lead, running and playing. Their exercise requirements are determined by their age, bread and health, so speak to your vet or vet nurse for advice specific to your dog.
Cats typically meet their exercise requirements by roaming around their local neighbourhood, but a growing number of cats are now being housed permanently indoors. This can have a negative effect on their wellbeing, but where indoor living has been recommended (e.g. if they have been diagnosed with FIV, a virus that could transmit to other cats), their food portions should be reduced accordingly and they should be given daily opportunities to play and climb.
Exercise opportunities for smaller pets, such as rabbits, guinea pigs and rats, come from the kind of living environment with which they are provided. These pets should be housed in living areas that are as large as possible to give them enough space to move around and exercise. Rabbits and Guinea pigs should have a sizeable, permanently attached run on grass ot provide lots of opportunities for activities such as climbing, digging and exploring. This can be achieved by providing tunnels, platforms, exercise wheels and digging trays.
