Biscuit the dog has a bent leg

Bend control arm at the very least.

Lower right back pain is commonly caused by damage or injury to the spinal structures, such as the lower right back muscles, the lumbar intervertebral discs, or the facet joints. While problems with these structures are more likely to cause centralized pain around the spine, it is possible that pain is felt primarily or entirely on one side of the spine.
Typical symptoms include:

• Limited range of motion (movements such as bending forward or turning to the side may be painful or impossible)
• Tenderness and/or swelling in the lower right back
• Lower back muscle spasms
• Pain that feels better with rest, such as sitting with both feet propped up and the knees supported and slightly bent-in an armchair with an ottoman, or in a recliner or propped up with pillows in bed
• Pain that feels better with ice or cold pack application
• Pain that resolves at least partly with over-the-counter NSAIDs, such as ibuprofen, and/or acetaminophen
• Pain that increases when getting up from bed or from a seated position

Remove the end cap. It has 3 legs which are hooked UNDER the inside rim of the outer speed dial ring.
These legs look like a one piece plastic part as if it belongs to the outer ring, but it does not.
The end cap legs can be bent inwards, i.e. away from under the speed ring,

Make sure you have good light, so you can see how the legs move.

With a flat screwdriver (fairly wide) bend back (twist the screwdriver gentle) all three to evaluate how strong they are and get a feel.
That also help loosening them.

I recommend to bend back one at a time and put small shims where the screwdriver goes.

While I was able to do it without, it with shims it will be easier to keep the legs inward.
Once you get two legs to come up from under the ring, you can get the entire end cap out.

Had to do this to fix the tilt mechanism. There was an inner nut that had came off the holding bracket. I suspect vibration made it come off , so I put some nail enamel on it after fixing.

The speed ring screws etc. are all accessible once you have the end cap off.

To get to the actual speed control knob, just unscrew the next little part, you'll see and it becomes obvious how to get at the rest.

Depending on which leg is bent, you should be able to move all legs so he sits properly in a sitting position on the floor. If this fails then lie him down as the legs can be moved while he is turned off.

Pull the legs out manually, sometimes when the dog falls over or is stores, the legs go weird. The head should fix its self when the dog is turned on.

We bought Biscuit and the legs turned in and he just laid there so we called Hasbro and they sent us another Biscuit and he did the same thing as the first one so I called them again (Hasbro) and they said it was out of warranty and there was nothibg they could do for me so now were just out of the money we spent on it and the kids have no Biscuit to play with I DO NOT recommend this toy to be bought for any child what a disappointment it is!!!!! Thanks

I pulled the skin back and the legs were bent inward. They are plastic framed legs and cannot be bent back into shape. Any thoughts on where to get replacement parts for him?

I found this on a review of the dog:
Playing with Lucky is pretty simple but does require some learning. Lucky is programmed to respond to 15 different commands but the commands must be issued the same way each time. First, you say Lucky's name to engage him. Once you say "Lucky" (or whatever name you give him) he will then respond to you with 2 barks. After he goes ruff-ruff, then you can tell him what to do. The commands are as follows: 

Speak to Me - he will sit or stand & bark 
Come Here - he will run forward and back 
Pounce - he will crouch and pounce excitedly 
Lay down - he will lay down on his tummy 
Sit - he sits 
Want a Treat? - he stands and barks (begs) 
On your head - He does a headstand 
Go to sleep - lays down, snores and enters sleep mode 
Sing a song - he'll bark one of 2 songs 
Good Dog - acts excited by shuffling his feet 
Bad Dog - he crouches down 
Put 'em up - he'll stand up on his hind legs. Then when you say "bang bang" he plays falls down and plays dead. 
Tug of War - he opens his mouth for you to put in his leash, he closes his mouth and tugs a little 

Lucky also comes with a "sleep" mode and automatically shuts off after not being played with for 3 minutes. 

Playing with Lucky is pretty simple, you command and Lucky performs. Well, Lucky performs most of the time. You need to be sure that he has your attention (barking twice) first before issuing the command. A few of the tricks are a bit more complicated - Put 'em up & Tug of War but the rest are very straight forward. I do notice that both my husband and I had the tendency to want to 'yell' or raise our voices when commanding Lucky - but that isn't necessary. 

Here's how I fixed mine... Looking at the inside closer, I realized that the ribbon tray (the metal assembly that the ribbon sits in) was bent upward in the bottom right hand corner; making the ribbon sit too high in the tray. I slipped a screwdriver under the bent area, applied presuure to straighten out the tray, and voila! It works fine now printing in both red and black. I'm guessing that people are are pulling back on the tray assembly when changing the ribbon resulting in slight bending over time.
