NEW TO ROVER: How do I start to get clients?

Check out prices in your area and make sure yours is the cheapest, or at least one of the cheapest, while you're starting out. That way, you can build up positive reviews, which will make clients want you more than people without reviews. Stay on your toes in the beginning - put a little extra time and effort into your first clients. They're taking a risk on you, so reward them. Arrive a little early, pay attention to how you dress/look, act professionally, send LOTS of cute, happy pictures and send them exciting updates, not just "he pooed this afternoon" lol. Gush about their dogs. Even if they're difficult, find things to love about them every day and report those things back to the owners. That being said, don't lie about difficulties. If their dog is a pain, consider whether they need to be informed or not. I lean towards 'not' unless the owner may have some techniques to help me or if there's a safety issue.
Make a "doggie" bag for your clients with various little goodies and leave it for them in their home when you're done walking the dog. It's one of those things that owners absolutely love - it's a nice surprise, it shows you care because you went above and beyond what was required of you. Plus, it has the added bonus of discouraging bad reviews - if someone didn't really like you, but you left them a cute treat bag (clearly going out of your way and leaving them with a very positive impression), they may forgive you enough to NOT leave a review, instead of leaving you a bad one. Most leave great reviews.

Another option: When I started, Rover offered a couple hundred free business cards. You can always get some, go to the park, and introduce yourself to people walking in the park. I hate this route because I hate talking to strangers, lol. But if you go this route, I advise against just handing them out, but actually observe the dogs, introduce yourself, ask about the dog, compliment the dog, maybe ask where they got the dog or if they're from the area, make sure they have a minute to get a (good) impression of you, THEN give them your card with an enthusiastic "if you EVER need someone to take care of this sweetheart, I'm actually a dog sitter and would love to take care of him/her." Maybe invite them to let their friends know, also. Make a note to yourself of all the people you meet so if they contact you, you remember them. (They'll be amazed.)

Best of luck!

I started about a month ago and to my surprise I am swamped. I had prices on average or slightly below others in my area, but now I am a little on the spendy side to try and slow business down a little and better reflect the amount of effort I put in. I also get every single client who I meet with, probably because I arrive on time and ask a lot of questions about their dog and how I can provide the best service possible.

I think asking folks who knew about my dog skills to write me a review helped get me started, but from there I think having decent photos and then a nice demeanor went a long way. I do tend to go above and beyond like extra walk time for energetic pups and little tips and tricks for folks. For now about half of my clients are going to be 5 day a week or nearly 5 day a week walk requests and the house sitting and pet sitting are starting to really take off too. I update my calendar daily and answer messages very quickly which may help with my search ranking.

Since you live near a park I would make sure you take your dog walk clients to places populated by dogs. I am good at training and got a few of my first clients by taking a dog walk client to the dog park (per their request) and chatting with folks or practicing basic obedience. I didn't have cards but wrote my promo code on a piece of paper.

Good luck and I hope you find success quickly.

Houston is a very competitive market for dog walkers so you should focus on making your profile stand out. I would change out some of your profile pictures as they aren't good, specifically the one with the glassy dog eye. What does "Full - time Professional Dog Lover" mean? Maybe your tagline should read Full - time Professional Dog Waker. Take and pass the Rover 101 quiz and get the badge. Also, you need a few more testimonials so ask a few friends and family to help you out. Passing out business cards to local pet stores and vets can help as does posting tear-off flyers on local bulletin boards. Best of luck to you

Does Houston have Quick Match for walks? It's a newer on-demand walking service (kind of like Uber for dog walks) that's available in some cities. You go through some online videos, take a quiz and have an in-person harness test. It really helped me build my clientele because I could accept walks and then starting getting lots of reviews which drove business for me.
