Blanco Diamond 33" Dual Mount Granite Composite Kitchen Sink, Silgranit, 70/30 Double Bowl, Volcano Gray, 443099

The BLANCO DIAMOND 70/30 DOUBLE BOWL DUAL MOUNT KITCHEN SINK features a 70/30 bowl design, offering plenty of room for rinsing, washing, soaking, spraying and straining operations. The 70/30 bowl split allows for washing larger items while still leaving the smaller bowl open. The smaller bowl is perfect for jobs that don't demand a lot of space; for example, thawing frozen foods or drying dishes in a small dish rack. The DIAMOND 70/30 can be installed as a drop-in or undermount sink. With an undermount installation, you can easily brush crumbs or wipe spills directly into the sink without dirt and grime building up around the rim. This kitchen sink is made of SILGRANIT, a patented, certified granite composite material engineered to take on the toughest kitchen tasks. SILGRANIT is heat, scratch, stain, chip, and impact resistant, making it stronger and more durable than other sink materials. It will not blister, burn, melt, or discolor from hot pots, pans, or baking sheets straight from the oven. Beautiful and highly functional with its non-porous, hygienic surface, it pushes away liquids and residue resulting in a low-maintenance, easy-to-clean, long-lasting material.The DIAMOND double bowl kitchen sink easily conquers the demands of everyday life.

Puppy loves these sticks!
Color: Dogwood & Calming, Size: Medium
Dogs love these sticks! Must smell and taste like real wood because it keeps my puppy from bringing real sticks in the house from outside. She is a heavy chewer and these sticks keep her occupied. We are on our 2nd set.

Our dog loves it but it wasn’t durable enough to last
Color: Dogwood Jack, Size: Large, Color: Dogwood Jack, Size: Large
Our lab took to it as soon as we gave it to her. Perfect size for our 80 lb yellow lab. However, now that it’s in about 10 days, she’s able to break off chunks from this bone that are dime size or larger, and we have to throw it away

No problems after a year and a half
Color: Dogwood & Calming, Size: Medium
Have been regularly buying these for my corgi for about a year and a half. The 2 pack lasts about a month or 2 each time. Pieces break off in small enough pieces that they safely pass through his digestive system. He gnaws each one down to about 1/4 the original size before we take it away and give him a new one. He continues to have regular bowel movements and has a healthy appetite so I can’t imagine any problems arising after so long. I have tried other alternatives and every other similar chew breaks off in larger pieces and didn’t feel comfortable letting him chew/eat them. I noticed there are a few 1 star reviews saying their dogs got sick off these but after a year and a half I have had 0 issues with this product. I guess it depends on the dog and how big of pieces they are swallowing. My dog ingests pieces about the size of a grain of rice so just pay attention and you should be fine.

Long lasting and safer alternative to sticks
Color: Dogwood & Calming, Size: Medium
These are great, very durable, and have lasted a very long time. Much safer for my dogs than the random sticks they find in the yard. They do get shorter with chewing eventually, but they don't break off in little chunks like I've seen with some nylon chews, and they don't splinter like wood. Medium size works well for both my 16 lb Cavalier and my 60 lb Pyrenees/Golden mix. They're both moderate-to-aggressive chewers, though size obviously affects how much damage they can do. I wish you could buy the hemp chew separately because that one is very much a favorite in my house, so after 2 years and 2 purchases, I have barely any left of the remaining hemp chew, but still 2 of the dogwood chews that neither dog is as interested in anymore. I'd love to buy a couple more of just the hemp one.
