What happens if you underfeed a Teddy dog?

Underfeeding a Teddy dog affects its physical development and easily causes weight loss, lethargy and a rough coat. Long-term malnutrition also lowers the dog’s immunity, making it more prone to illness, and chronic hunger can damage the stomach and cause gastroenteritis.

If the dog is occasionally overfed, it may become very excited and eat too much at once, which can disrupt stomach function and lead to acute gastroenteritis.
