Your poor dog sounds very sore!
When I hear that a dog is lame in a front leg AND a back leg AND also is painful when picked up it tells me that your dog has a neck problem. This is most likely going to be a disc problem between the vertebrae or possibly in a dog of Jerry's age some worsening of arthritis in the neck region.
You can try moving his head around to see if it is painful. You need to turn his head to either side quite forcefully (but gently!) until his chin touches his shoulder. Also lift his head up and down so that his chin touches his front toes. Sometimes this will cause a painful response but sometimes even this will not show a painful response - depending on where the problem is in the neck.
Are you able or likely to go to your vet? How many hours until they are open (I am in a different time zone)?
If you are not able to get to a vet for 12 hours or so (and your dog is eating and drinking ok) then you could try him on some pain relief to help him. The simplest medication you can use at home is acetaminophen (Tylenol). Dose rate is 10mg/kg bodyweight or 5mg/lb body weight twice daily. I would only do this for a maximum of 2 doses.
I hope this helps and let me know if you need further assistance.
