• Try to exercise your dog more often. Maybe you could walk your dog earlier in the day- this way you will be more inclined to getting around to it!
• Try to cut back on treats and tit bits. Remember that some treats can be very rich in calories!
• Avoid overfeeding your dog... The recommended average amount to feed is 100g or 3oz of dry dog food per 5kg or 10lb of bodyweight. For Example - If your dog weighs 20kg, they should require around 400g of food per day. Splitting this into two meals as 200g in the morning and 200g in the evening would be a good idea. Please note however that the amount to feed may vary slightly depending on how active your dog is.
• Reconsider your dog's diet...Fibre is a very important consideration- The majority of commercial dog foods contain very little fibre, because they are made up mainly from starchy cereals, which often means a high level of carbohydrates.
• Increasing the fibre in your dog's diet will help him or her to achieve a feeling of fullness (from the extra 'bulk'), and they will also maintain the feeling of fullness for longer because fibre is digested more slowly in comparison to other ingredients such as starchy cereals.

Fibre also has a lower energy content (in comparison to other ingredients in dog food, like starchy cereals), so opting for a diet that contains ingredients which are naturally higher in fibre, rather than starch and carbohydrates is a good idea; as this will mean fewer calories.
