I have an 11 week old doxi and a 7 year old doxi,they both love to chomp at knotted rawhide and even play tug of war with it,I find this great as they are bonding well together,I just want to know how much rawhide shuold I be giving them?

None, zero, zip! The pet stores are full of toys that many dogs will quickly chew up into
Pieces they could choke on or cause intestinal blockages. If you are not
There to watch, stick to sturdy stuff such as Nylabones and Kongs. Keep a
Close eye on chew toys and quickly discard anything that is coming apart in
Pieces. Rawhide is especially bad because it swells after being swallowed.
I don't trust any of the consumable chews. The dogs just gnaw them down to a
Dangerous size too quickly. These problems are the worst with, but not
Limited to, large, aggressive chewers such as Labs.

Ropes from the pets' store quickly turn to hazardous shreds. Ones I made
Lasted much better. Go to a hardware or home center that sells rope by the
Foot. Buy 2' of 3/4" poly rope. Melt the ends, and tie knots in it. Get
Them as tight as possible, put it in a vise and pound it with a hammer. Watch
Carefully, and be ready to discard when it comes apart.
