Not sure how we can relate this episode with the recent visit at the groomer but generally speaking, considering what you described, that could be related to dietary indiscretion.
As a first line approach, I would suggest to withhold food for the next 8-12 hours and then start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days.

I would definitively recommend a veterinary check up if the signs persist or you notice diarrhoea, more vomiting, lethargy or inappetence.
Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
