History: An eight-year-old, spayed female Labrador retriever presented for evaluation of acute onset of diarrhea and collapse. The owner reported that the dog was completely normal until 3 hours prior to presentation when the dog developed profuse bloody diarrhea. There was no history of toxin exposure, and current medications included prednisone 1 mg/kg orally BID, famotidine 0.5mg/kg orally SID, and azathioprine 10mg/kg orally SID for immune-mediated hemolytic anemia diagnosed 4 weeks prior.
On initial physical examination the dog was recumbent with tacky, muddy mucus membranes and a capillary refill time of approximately 3 seconds. The rectal temperature was 98.9° F, pulse 180 beats per minute, and respiratory rate 60 breaths per minute. A large bore over the needle catheter was placed in the cephalic vein and the following minimum data base was obtained: PCV 34%, TP 5.4 g/dl, venous lactate 7.4 mmol/L. The dog had severe pain on abdominal palpation and there was a palpable abdominal fluid wave. An abdominocentesis was performed and the abdominal effusion was found to be a transudate. The remainder of the physical examination was non-remarkable. An emergency abdominal ultrasound was performed.
Describe the lesion outlined in the ultrasound image:

History: An 8 year old, 30 kg, mixed breed dog presents with recent onset of left hind leg lameness. Radiographs and subsequent biopsy reveal the presence of an osteosarcoma of the distal femur. The decision to amputate the limb is made. How would you manage this dog’s acute perioperative pain using a wound soaker catheter? Calculate doses and volumes of local anesthetic needed to maintain pain control, and duration of treatment.

Background: Boomer, a 7 year old, CM chocolate Labrador retriever was evaluated to determine the cause of chronic right forelimb lameness of 3 months duration. The lameness was not responsive to medical management consisting of rest of 4 weeks duration and NSAID treatment.
Gait evaluation revealed mild right forelimb lameness at a walk, and moderate lameness at a trot. Physical examination revealed mild elbow effusion, and discomfort with elbow flexion and extension, particularly with supination, as well as pain with shoulder flexion and extension.
Radiographs of the right elbow were obtained (Figures 1 A, B, and C).
What is your radiographic interpretation, and what if any, further workup would you suggest for Boomer?
What medical or surgical treatment options would you recommend?
