I have two dog that are limping quite bad. 1=female black lab approx 5-6 yeas old, about 75 pounds. Usually after a walk her back hips hurt for a day- but she is limping on her front this time... I have checked her right paw...I do not see anything in it. I press all around her paw and she does not give me sign of pain. It has been this way for a day now. However, when I go up the paw toward the (ankle) ??? _l she will whimper. Also, when she gets up from laying on the floor. Any ideas?

The 2nd dog is a 95 pound male approx. 3-4 years old- boxer, bull mastiff mix. He has been limping on his right front leg for 3-4 weeks now. Again, nothing visible or touchable in the paw. I can squeeze the paw, going all the way up to the trunk of his body- he gives no indication of pain or discomfort.   The vet said he needed to lose weight and that was the cause. Buddy is and always has been very healthy and in shape.

Since winter, we have not walked them on a regular basis. But we do play with them constantly and take them for rides to the park regularly.
