More Than Just Size
Small dogs bring big joy, but caring for them means more than enjoying their tiny size. Their needs can be different from larger dogs. Here are some key points to think about:

- Health: Some tiny breeds have specific health issues to be aware of. For example, dental problems, fragile bones, and breathing difficulties can be common. Regular vet visits and a good diet help keep them healthy.
Small dogs need time and attention beyond their size. Grooming keeps their coat clean and free from problems. Training stops them from developing bad habits. Health care helps spot issues early.
