The Sheltie is no different to any other puppy, and when it is first brought to it's new home it will be feeling a little insecure. Your new puppy will have left the security of it's mother and brothers and sisters and will be wondering what's happening. It is very important to give him/her a lot of love and affection at this stage .
Your puppy will soon learn that it can rely on you to protect it from danger, feed it, groom it and love it - just as mum used to do. As soon as possible, take your new puppy to your veterinary practice to have it thoroughly checked over and complete a course of vaccinations. As it takes a while for the injections to become fully protective, your puppy will have to remain in it's own house and garden for quite a few weeks.
The length of the Sheltie's coat demands a good daily brushing to maintain it's good looks. Your dog's coat is very important, as it keeps the heat out in summer and the cold out in winter. Try not to bath your dog too often. The Sheltie's skin is very rich in oil glands, which not only prevent it from becoming dry, but also help to keep the coat water-resistant.
If your dog gets plenty of exercise there is not usually a need to clip the claws. However, should you need to, your veterinary practice will show you how to do it safely, and without discomfort to your dog. It is advisable to start to brush the teeth at an early age - it will prevent trouble in later life. Hard biscuits and hide chews will help to keep the teeth in good condition.
Of course these are the very basics in caring for your Sheltie. You will learn a lot by experience and soon you and your dog will learn to communicate whenever there is a problem.
