Can't say my experiance was as positive! I used them for about 4 years, then changed in Dec last year as found the quality was slipping. My issues were..
My dogs often stopped eating the chicken carcasses, and I had an entire order that smelt worse than usual that I wouldn't even offer the dogs. They did swop them for me, but at first Janet told me to throw the old ones away then when it came to them replacing them (next delivery day) they would only do so if they collected the off ones! Luckily I still had them in my freezer, but only as I had not had time to dunp them.
The trotters smelt bad too, and still had straw between the toes - Do they not wash them! Dogs wouldn't eat them.
Rib bones with hardly any meat on. Didn't smell though, but probably due to the lack of meat!
When they didn't have any chick mince they sent me lamb instead with no phone call. I don't feed it so as you HAD to oder 36lb (or 18x18) this left me very short that order.
The mince I found ok, but my dogs did turn their nose up at that from time to time.
So in the end all I was ordering was the mince, so needed to find somewhere else. I did hear from lots of people who got wrong orders, or where there order didn't turn up at all, but that only happened to me once of twice. But the quality I found to be awful in the end.
I now use The Dog Food Company
http://www.thedogfoodcompany.co.uk/products.html MUCH happier. The meaty bones are really meaty, everything always fresh - often being slaughtered the day before delivery, and not frozen! Trotters no straw lol Nothing has ever smelt and you can order as much or as little of the mince as you like. Also do rabbits :o)
Hope this helps give a different opinion of them.
