The Sealyham terrier’s food should be balanced and rich in proteins, vitamins, minerals, and other nutrients to help him grow healthy and strong. Proteins are needed for the development of your Sealy’s tissues, organs, and muscles. Proteins also help to prevent illnesses. The proteins must be of high quality and should compose of more than 25 per cent of his daily food requirement.
Glucids make a vital contribution to your Sealyham terrier’s healthy growth. Glucids are generally found in cereals and a good source of energy. Essential fatty acids are also important for the development of your Sealy’s nervous and immune system. Essential fatty acids should be preferred as a source of energy rather than carbohydrates. They are easily digestible and provide vitamin for your Sealy. Calcium is also needed for healthy bones.
The Sealyham is quite athletic, so opt for an excellent-quality dog food that will replenish his energy. Choose one that is specifically created for his age, breed, energy levels, and size. If you are having difficulties in deciding, ask the vet for help.
Do not go for commercial dog food. Whilst it is a cheap option, it contains insufficient amounts of calories and nutritional content. It can cause vitamin and mineral deficiencies in your dog. Other commercial dog food brands also contain dubious ingredients such as preservatives, which can harm him. Fresh water should be available throughout the day to prevent dehydration.
Follow a set mealtime consistently, and feed the same food that your Sealyham terrier is used to in order to avoid stomach upsets. A Sealyham puppy must be fed three to four times a day, whilst an adult Sealyham terrier can be fed twice a day.
For a two- to six-month-old Sealyham puppy, feed 125–173 g of food daily, depending also on its size and activity level. For a seven- to ten-month-old Sealyham, feed 121–132 g of food daily. When it turns eleven months and beyond, it can be given adult dog food.
The adult Sealyham weighing 8 kg should be fed about 115–134 g of food daily, also taking into consideration its activity level. For a Sealyham terrier that weighs 9 kg and above, the daily recommended portion ranges from 126 to 146 g.
