Good morning Ms Yeung! I would not give this supplement to Mochu if it contains D3. Too much vitamin D can be toxic to dogs, as it causes hypercalcemia (increased blood calcium) which can lead to kidney failure, haemorrhage, and tissue mineralization in the heart, liver and kidneys. She will be getting all the vitamin D she needs from her food, and too much will not be good for her. It's fine to give her Omega 3 supplements, but make sure they don't contain extra vitamin D. With the omega fatty acids, she can have 1,000 mg fish oil containing 300 mg of EPA/DHA combined for every 30 pounds of body weight. I hope this helps :-)
