My 140-pound dog had a broken nail surgery last month it has been a big challenge for me to bring him in and out since then. Fortunately, I found this US website after having talked with Melissa, the customer service, I placed the order for this product. The delivery is super fast, and the quality is the best! It enabled me to carry my boy easily after he had his second surgery last week. One more point I would like to address here is I feel it is a very reliable company I actually thought ordering a more expensive and complicated tool to help my boy walking however after giving detailed information Melissa provided me a more practical solution with much less spending, they do care their customer!
