If you are not home during the day, your dog should be kept secure in a dog-proof fenced yard and should never be left unsupervised when tethered. In the case of larger properties where this is not possible, then an appropriately fenced dog-run should be constructed, and the dog kennel, along with a plentiful supply of fresh water, should be placed within the run.
It is important to note however that dogs who are never, or seldom allowed indoors, are more likely to become bored - and as a result become disruptive (e.g. bark for attention) and/or destructive (e.g. dig up your newly- planted rose bush). This is because dogs associate their human family as their pack and can develop behavioural issues if they feel neglected as a consequence of being excluded from interacting with their pack.
However, if you decide to keep your dog outdoors, it is important to consider how you'll ensure it receives the appropriate amount of human contact (particularly during those cold winter months in which we'd all much rather stay snuggled inside rather than playing fetch with our pals in the cold!). An option could be to enlist the service of a dog walker. Also, if you work long hours or are sometimes forced to take overnight trips, it may be useful to consider "doggy day care" facilities to ensure that your dog receives the TLC and companionship it will need in your absence.
Combing and brushing dogs regularly is essential, particularly for longhaired breeds. It is best to establish this habit early in a dog’s life so that grooming becomes part of the routine. Grooming removes dust, dead skin, loose hairs, grass seeds, and tangles. It also assists to shorten the coat moult, which occurs every autumn and spring. Brushing helps keep your dog cool in summer months and reduces the amount of hair your dog sheds. Dogs with short coats also require some brushing.
