Life is all about balance. Yin and Yang must be in balance to achieve optimal health.
Some pets are hot, having a “Yin Deficiency”. Yin supplies cooling and moisture. When the cooling system doesn’t work well, signs of heat will appear. Yin Deficient pets will show signs of excess heat in their body by panting, drinking excessively, and having a dry coat, nose and pads. The tongue and gums will be red or dark pink and may be dry.
Other pets may have the opposite problem – they are cold. Since “Yang” means warm, pets who are cold have a “Yang Deficiency”. This is seen commonly in older animals and in thin animals. Yang supplies warmth and energy, so many times these animals have difficulty getting going. They may lie down a lot, have weak hindquarters (with or without arthritis), and move slowly with the hind end lower, almost crouched. These pets rarely pant (unless stressed) and have a pale, wet tongue. They may have a drippy nose.

Eggplant is one of our kitties. She is middle aged and her favorite place to sit or sleep is on the heat vent. She finds every sunny spot in the house and loves to lie on the lounge chairs by the pool on 90-degree summer days in full sun. Our older dog Freckles wears a coat all year long. She has weak hindquarters and leaks urine. When fed meals that are warm (temperature) and warming from the interior (Yang tonics), her urine leakage is much less. If we feed her “Yin tonics”, or cooling foods, she leaks huge puddles of urine and has more hind end weakness.

Foods that can help warm pets (and us) from within include venison, lamb, chicken, goat, pheasant, kangaroo, kidney, oats, white rice, ginger, cinnamon, pumpkin, garlic, hawthorn, sweet potato, and turmeric. By feeding a diet using a warming protein base, we can contribute more energy to these pets by warming from within.

In contrast, foods that help cool pets from within include rabbit, duck, cold water fish, pork, apples, asparagus, melons, barley, kelp, and crab. By feeding a diet using a cooling protein base, we can help pets suffering from internal heat. External cooling with fans, air conditioning, and cooling mats will also keep these pets more comfortable.
A new bed, the Cozy Vent,  has been developed that fits over heat or air conditioning vents on the floor to help pets that are too hot or too cold. Check it out! Available on Amazon and also available in my webstore.
