Doepfer A-138b Logarithmic Mixer8HP Logarithmic mixer for mixing up to 4 signals to one output. Works best with audio, but CVs are possible, too. If the first input is not connected you can use the first potentiometer as an offset control for creating a constant offset voltage. By a jumper you can determine if the offset is active and if it goes from 5V to 0V or from 0V to +5V.

It's OK.
Color: Red
My dog chewed the bottom clean off in 10 minutes. He's a medium size dog. He likes it, it's just not going to last long. I bought one as a gift as well and that dog did the same thing, bit the bottom off in no time, so while it's a nice toy, watch for choking.

My teething dog loves it!!
Color: Blue
I purchased this dog toy in both the red and the blue and it is my 8 pound puppy’s current favorite toy. She is teething and working away at trying to get those adult molars to come in.
It is approximately 6 inches long and the description says it is for large dogs but I feel that it would be more appropriate for medium to smaller sized dogs. It won’t stand up to really tough chewers. My puppy has already chewed off a few of the little leaves that surround the rose. There’s no squeaker but there are tons of little nubs that make chewing fun and teeth healthy.
With the amount of enjoyment that my puppy is getting from this toy, I feel it is a good value for the money.

Dogs love them!
Color: Blue
I had to by one for each one of my dogs after purchasing the first one for the new puppy. All three, pink, red, and blue are the same size fyi. Dogs love them and they seem very durable for my heavy chewers.
