My dog is limping and not moving much, but eating. Should I worry?

He really needs to see a vet. You didn’t mention if it was a front leg or hind leg. He could have a simple strain/sprain. It could be a genetic OCD lesion or hip dysphasia. It could be a torn CCL if it’s a back leg. There is no way for us to diagnose this via the internet. He needs to be examined by a vet in person. It sounds like he’s in pain and that’s why he’s not eating.

Lameness, loss of appetite and energy are definitely concerning. This can be caused by tick borne diseases such as Lyme disease. There are also certain bone and joint diseases that only affect growing puppies, and need to be ruled out with an x-Ray. I recommend having your appointment sooner rather than later, you may want to call your vet and ask for an earlier appointment.

If it just started you can let Bruno rest for a few days with minimal walking and minimal physical exercise, if it does not improve within 3-4 days you will have to take him to the vet in order to get it checked and treated, he might need pain killers for a few days. if the vet think it's something more serious such as a fracture, joint injury or foreign body, he might recommend to have an xray done as well.

If he was behaving normally otherwise, then watching him at home would have been recommended, but since he is lethargic as well, he really should be seen. It could be anything from a strain or pull to orthopedics injury to infection. A physical exam, xrays and a screening for tick borne diseases would be recommended. Treatment will depend on the diagnosis. In the meantime, restrict activity to just leash walks for elimination and avoid excessive running, jumping or rough play until he sees the doctor.

Poor Sparky is in pain if he's limping. I recommend resting him for the next 48 hours. No running, jumping, or playing. Take him out to toilet on a leash, and bring him right back in when he's done. If he still appears painful after this time, then I would take him into the vet for an exam. The vet can diagnose where the pain is coming from, and can dictate a treatment plan for it. He may also benefit from some pain medications, which the vet can prescribe. Please do not give him any human pain medications, as many are toxic to dogs and can be fatal if given.

If Paxton is not eating at all and is limping, this is a sign he is in pretty bad pain or badly injured. I would try to find a vet that can see him sooner, or get in to an emergency clinic (your wait may be several hours as he is not an immediate triage case). Until you can get him into a vet, keeping him on strict bed rest to avoid further irritation or injury of the leg, and offering some bland meals like boiled chicken and rice may help get him eating and reduce his pain, but it is best to get into a vet ASAP if he still refuses.

Limping means Rocky is in pain, and if he's not eating as normal and not drinking, that tells me he is in a lot of pain. Unfortunately there are no OTC pain medications you can give him. Many human ones are toxic to dogs and can be fatal if given. I'd take him into a vet now to get treated.
