We have a large/giant breed dog 50kg, definitely not overweight just a really big bo. These biscuits are the perfect size for him, they don't get stuck under his lip area like some of the smaller biscuits do,he loves this food. Hoping it could come in a 18-20kg bag in the future. Well done Optimum, good for large/giant breeds.

This product is great for my Staffi/Rotti, she really enjoys the large kibble. This is the 2nd time I have bought from Pet Circle and I will continue. Great value for money and whilst doing my usualweekly shopping I have told others about Pet Circle and their fast delivery.

Pet post is a fantastic way to shop. I buy a 15kg bag of large piece kibble for my Samoyed. You can’t get this product in supermarkets and I am glad because I would have difficulty carrying it. Pet post is very fast with delivery- usually no more than 48hours from time of ordering.

My dogs have sensitive stomachs. This is the food that has their stools nice and hard and doesn't make them itch. Very happy with the price here too. At the shops it's $25 for a 3 kg bag, was costing me a fortune.Will purchase from here from now on.
Like most Cocker Spaniels, ours scoffs his food immediately. Putting this kibble in a large Kong Mike toy makes him slow down and keeps him entertained for a few minutes. I use the top end of a cut off soft drink bottle as a funnel, to fill the Kong.
Great product, love the larger biscuits to help with dental care, loving the convenience of auto-delivery. Perfect for all large breed dogs
My two working dogs love this product. It is also large enough to assist with keeping teeth clean.
My Samoyed loves his kibble. The large pieces are perfect to provide bulk with a raw meat meal or as a treat. They are the so big and crunchy and can substitute for a biscuit. The 15 Kg bag lasts him approximately three months. The large kibble size is not available in supermarkets, nor have I ever found it in the pet store.Great value, great convenience.
I was looking for no artificial flavours and colours as well as Glucosamine for joint health. I found it in Optimum Adult.
The large sized pieces mean our boy has to slow down to chew them which helps him eat dinner that little bit slower!
