We started our morning at Frontier Veterinary Urgent Care a little differently today! 🐾💙

Before opening our doors, our team came together for our quarterly all-team meeting. It was a great opportunity to connect, share updates, talk through goals, and make sure we’re all on the same page as we head into another busy season.

And because every good meeting deserves a celebration… we also took some time to celebrate Dr. Marquart and her growing family! 🍼💕 Our team (under Nellie's direction) put together a fun baby shower complete with games, decorations, and plenty of laughs!

We’re so grateful for the people who make up our Frontier team and for the opportunity to celebrate these special moments together. 💙

Congratulations, Dr. Marquart! We’re so excited for you and can’t wait to meet your newest little addition! 👶✨

🐾 CUTENESS ALERT! Meet Sock! 🐾

Sock is a sweet 4-week-old kitten who came to see us after having a decreased appetite and diarrhea. At such a young age, it’s important to take changes like these seriously!

Sock was evaluated by our team and received the care he needed. 💕 We’re so happy to help this little guy get back to feeling his best!

Sending lots of love and good vibes to this tiny fighter! 🐱🧦💙

🎉💗 Happy 1st Anniversary, Megan! 💗🎉

We can't believe it has already been a year since you joined Frontier Veterinary Urgent Care! 🩺🐾

It has been amazing to watch you step into the Practice Manager role and hit the ground running. Your eagerness to learn about veterinary medicine and our business processes has been truly appreciated. Thank you for always having our team's backs, supporting our staff, and leading with kindness and compassion. ❤️

The care and empathy you show to our patients, clients, and teammates every day never go unnoticed. 🐶🐱 Your positive attitude and willingness to jump in wherever you're needed make a difference in so many ways.

And, of course, thank you for introducing us to Sally and making her the official Frontier mascot at our events! 🎀🐷 I don't think our clinic had ever seen so much pink until you arrived—and we wouldn't have it any other way! 💕✨

Thank you for everything you do to make Frontier such a special place. Here's to an incredible first year and many more to come! 🥳🎉🐾

💕 Sally is no stranger to Frontier! 💕

Our sweet friend Sally recently came to see us after she suddenly started shaking and didn't want to move. It was clear she wasn't feeling like herself, and her family knew something wasn't right.

Our team performed X-rays to rule out any serious injuries, and thankfully there wasn't anything significant found. After a thorough examination, it was determined that Sally was experiencing back pain, which can be fairly common in dogs with long backs.

With some rest, pain management, and lots of love, Sally is on the road to feeling better! ❤️

We always love seeing Sally (even though we'd rather it be under happier circumstances!), and we're so glad we could help get her comfortable again.

If your dog suddenly seems painful, is shaking, reluctant to move, or isn't acting like themselves, don't ignore those signs. Pain can present in many different ways, and having them evaluated sooner rather than later can make all the difference.

Feel better soon, Sally! 🐾💙
