Let Us Make Your Gem Sparkle!

At Diamond Dog we strive for excellence!  With over 20 years of grooming & training experience we have the ability to work with animals with health issues as well those with behavioral issues. Owner Gail Grungo’s years of experience as a veterinary technician enables her to recognize common health problems with her clients that can be overlooked by other groomers and alert their owners. The staff are able to work with animals that most other places would not be willing to work with.


We offer Grooming, Training and Boarding services. If you would like to learn more about our services feel free to check out our website more indepth. We also believe in the personal touch and welcome speaking with you in person or via phone.



Typically when your pet is groomed they will stay for some time during the day unless you speak with us to make speacial arrangements. We would love to be able to get everyones pets out early if we were able! At the time you book your appointment please make us aware if you have time constraints and we can see if we can get your pet out in a timely manner. We ask that you remind us the day you drop off your pet for your appointment.


Make us aware if your pet gets stressed from the grooming process or has medical issues so that we can work within your pets capabilities. We typically close when the last animal is picked up for the day so the time can vary dependent on how busy we are that day. We ask that you give us a call during the day to check in with us on your pets status and time their grooming will be completed.


We would love to meet your furry family members! We do try an accomodate last minute bookings but we recommend you make your appointments in advance since we book up quickly especially on Saturdays and the holidays. Contact us today to book an appoitment. Give us the chance to Make Your Gem Sparkle!
