Pet care experience

I'm a proud pet parent to a lively Pomsky and an avid pet lover graduated from UCDavis VET. My wife and I tend to our pet companion together, fostering a warm, nurturing home environment. I have gained substantial experience from my time at an animal shelter and have also volunteered in various countries for animal services. Being well-versed in pet emergency handling, you can trust me with your pets, regardless of their size or energy level. Let me put your mind at ease by offering my expert care to your beloved pets🤗 In addition to providing boarding services, I also offer pet washing services. This includes a full bath at the end of the boarding period. Please let me know if you're interested in availing of this extra service. Before You Book: • Earliest drop-off time is 8:00 AM. • Food and medications should be provided by the owner. • We provide dog bowls, toys, and extra dog beds. • Bringing your dog’s own bed is optional. However, please keep in mind that some dogs may chew, damage, or soil their beds while adjusting to a new environment, so I cannot guarantee that personal items will be returned in the same condition. • Please let me know in advance if your dog has separation anxiety, escape tendencies, resource guarding, or any special care needs. • For everyone’s safety, all dogs must be friendly with people and able to be safely managed in a home environment.

William and his wife did an excellent job in making my kittie feel welcome during his stay. They sent fun pictures each day. Will definitely look to book them again.

Junior had a great time with William and Yue! They made sure to make him fee home and play with him. I also loved all the photos and videos I was being sent throughout the stay. We'd definitely recommend them! :)

They took great care of my dog and they sent lots of pictures during her long 10 day stay. They were very responsive and most importantly, my dog looked like she was having a great time and came back happy and healthy! Will definitely use them again!

Wow wow! We’ve never left our dog for more than 3 days (and always with people he knows) so we were super nervous. But holy cow! The most exceptional care for our little buddy Bowie. Daily pics and videos. Playtime. Cuddles. Love. We picked him up and he was confident and loving, clearly signs of caregiving that was intentional and active. What a great experience for him. And us! Could not give higher praise for William and his family. They have several dogs on site that were full of love, energy, play, and acceptance of Bowie. We look forward to future experiences together!!
