What Petland Customers Are Saying
“From my first visit, this place worked miracles. I went on their website to see what they had and decided I wanted a certain male Yorkie puppy. When I went in, I just browsed around a while before a young lady walked out with the very puppy I had come to adopt. Over the next year, Chewy and I became best friends, but something was missing for him. After a year, I went back to pick out a little sister for him, Stella Mae. This is a wonderful place with very knowledgeable staff. Both times, they were very thorough and made sure that I understood all of the paperwork, including the warranty. Both have been 100% healthy the entire time I’ve had them. I recommend Petland to everyone.”
“My wife and I were looking to get her a puppy for service dog training. She has been waiting since 2016 to get this opportunity. Madeline and another kind gentleman helped us out and were patient, informative, and helpful in all of our inquiries. My wife found an amazing fit and as her first puppy. She got all her questions answered and walked through the whole process. Kind people working here and would recommend to anyone.”
