These tricks can be used by themselves, or in combinations. Add water to the food, whether it's dry or canned. Start slowly, and proceed as your pet's appetite permits. If you have food available all the time, feeding your pet two meals a day before you start adding water will help it accept the water more readily. Place water next to the food.
Some animals prefer a full, shallow dish, others seem to like reaching down into a container.
You can experiment here to find out what your pet likes best. Offer distilled or bottled water. Leave some water in the bottom of a sink, bathtub or shower. Putting a shallow bowl under a slow drip ensures a drink of fresh water whenever your pet wants one. Make ice cubes out of meat or fish broth.
