Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern! Any time I have administered a vaccination and the animal then begins vomiting or exhibiting any other abnormal symptoms, I treat as a potential adverse vaccination reaction. I would recommend taking him back to the veterinarian that performed the vaccination to have him examined and treated for a potential vaccination reaction. This may have nothing to do with the vaccination but it would be best to have him examined and go from there. I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Depending on how many times your puppy has vomited, it may or may not be a cause for concern. Just like people, dogs can occasionally have some gastrointestinal upset that may be transient and pass. The Rabies vaccination is not likely to be the cause of this as typically these reactions are seen shortly after the administration of the shot. If your pup is experiencing a post-operative infection from the spay procedure, vomiting could potentially be seen depending on the severity of the infection. I would expect other clinical signs to accompany this as well though, including lethargy and a fever, as well as redness near the incision site. If you aren't seeing any of this, my suspicious is that your puppy may just be having some indigestion. Consider fasting him for the next 12-24 hours then feeding a bland diet for the next 3-5 days. As long as things continue in the right direction from this point forward, I wouldn't lose too much sleep over things. If the vomiting you are seeing at home is chronic, I would definitely recommend taking him to see a veterinarian at once for a diagnostic work up.
