A Welsh Terrier's coat is moderately long and they have a double coat with their top coat being harsher to the touch, whereas their undercoat is dense and that much softer. As such they need to be groomed regularly to keep any shed hair under control and ideally this has to be every day. They also benefit from being taken to a grooming parlour two to three times a year for their coats to be hand stripped which makes keeping it tidier and in good condition that much easier in between visits to a professional groomer.
It's also important to check a dog's ears on a regular basis and to clean them when necessary. If too much wax is allowed to build up in a dog's ears, it can lead to a painful infection which can be hard to clear up. In short, prevention is often easier than cure when it comes to ear infections.
The Welsh Terrier may be small in stature, but they are known to be energetic characters. They are also very smart which means they not only need to be given the right amount of daily exercise, but these little terriers need to be given a ton of mental stimulation on a daily basis too. They need to be given anything from 60 to 80 minutes exercise a day and more if possible because there's nothing these terriers like more than to be in the great outdoors doing something.
A shorter walk in the morning would be fine, but a longer more interesting one in the afternoon is a must. These dogs also like to be able to roam around a back garden as often as possible so they can really let off steam. However, the fencing has to be extremely secure to keep these active little dogs in because if they find a weakness in the fence, they will soon escape out and get into all sorts of trouble.
With this said, Welsh Terrier puppies should not be over exercised because their joints and bones are still growing. This includes not letting a dog jump up and down from furniture or going up or down the stairs. Too much pressure placed on their joints and spines at an early age could result in a dog developing serious problems later in their lives.
If you get a Welsh Terrier puppy from a breeder, they would give you a feeding schedule and it's important to stick to the same routine, feeding the same puppy food to avoid any tummy upsets. You can change a puppy's diet, but this needs to be done very gradually always making sure they don't develop any digestive upsets and if they do, it's best to put them back on their original diet and to discuss things with the vet before attempting to change it again.
Older dogs are not known to be fussy or finicky eaters, but this does not mean you can feed them a lower quality diet. It's best to feed a mature dog twice a day, once in the morning and then again in the evening, making sure it's good quality food that meets all their nutritional requirements. It's also important that dogs be given the right amount of exercise so they burn off any excess calories or they might gain too much weight which can lead to all sorts of health issues. Obesity can shorten a dog's life by several years so it's important to keep an eye on their waistline from the word go.
