If your puppy is just one month old, it is still a very fragile and vulnerable puppy. If it vomits, you should get medical help as soon as possible and keep your attention. Here are some suggestions for dealing with puppy vomiting:
Give your puppy plenty of water. Make sure your puppy has enough water to drink to prevent dehydration. Remember, puppies need to drink water regularly because their bodies are not fully developed yet.
Observe the puppy for other symptoms. If your puppy has other symptoms, such as loss of appetite, diarrhea, laziness, or fever, he or she needs to seek medical attention as soon as possible.
If the puppy continues to vomit, please see a veterinarian. If your puppy vomits continuously, or vomits for more than 24 hours, you need to find the nearest hospital and professional veterinarian as soon as possible.
Please note: Puppies have very delicate bodies, so do not wait for symptoms to worsen before seeking medical help. If you have any questions about your puppy's health, consult your veterinarian or seek emergency medical help.
