Poor guy. He is a bit young to have muscle weakness, so this is a bit concerning. I would highly recommend taking him to your vet to have his legs examined first. He may have an underlying disorder that is causing this, such as myasthenia gravis, a muscle injury, or something else entirely. Once the vet is able to diagnose the problem (using testing such as bloodwork +/- radiographs), then we will know what Lucky needs for treatment of his conditon. Also make sure you aren’t giving any kind of supplements to him, such as calcium, which can potentially cause musculoskeletal disorders in pets. Also feeding him a high quality puppy food such as Royal Canin, Hill’s science diet, Evo, Eukanuba or Merrick is also ideal for proper bone and muscle growth. I hope are able to find the issue soon and get Lucky feeling better. Best wishes and take care.
