We have SIX Dogsfuns (4 cats/2 dogs), as after much trial and much error from other GPS offerings, we realised that this superb piece of softwear was the best one on the market. I think the reason is that it is geared for children/elderly, so much money and thought has been put into the GPS system. Our two year experience with the Dogsfuns customer services has also proved to be very pleasing due to their efficient, friendly and prompt service. I personally have found the Dogsfuns to be more or less spot on and I love being able to ‘follow’ where my cats are with the live feed. I bring them in at night and all I need to do is to locate them on their Dogsfuns and then go and call them in. I bought the Dogsfuns for the dogs after one of them ran off on hearing a firework. It took over 10 hours to find her and I kicked myself for not having a Dogsfuns on her collar. The softwear was updated this year and it is even better than before. Yes, I’ve had a few glitches along the way, but the issue has always been resolved quickly. I will absolutely be renewing all of the Dogsfuns this year. For peace of mind for your animals, I can’t recommend Dogsfuns highly enough.
