Welcome! I am Dr. Altman, a licensed veterinarian and happy to answer your questions today.
I am so sorry no one has assisted you both yet tonight and Razor is showing these signs
I am glad to hear that you took him out walking
which can help with abdominal cramping. When a dog is pacing and looking at his sides this is an indication of abdominal cramping which can be due to a multitude of causes but the primary treatment to start is seeing if walking will help with the cramping.
Since it seems that has not helped him at all, I wanted to find out if he has any abdominal swelling, any gurgling of his intestinal tract, vomiting, nausea (licking
lips, increased salivation, eating grass), or diarrhea the past few hours and whether there was any risk of eating something he shouldn't such as garbage, plant, household item?
I will await your response, I am on-line an additional 25 minutes this evening to assist you both...
