Hi all, I'm first time dog owner. My dog just fell from about a 3 feet table and he is teacup poodle, 4 years old and 6 pounds. His rear right leg is swallow a bit but he is still walking. When he walks, he is hiding his right leg and only 3 legs walking. Is there anything that i could give him until i take him to the vet? please help me! Thank you so much!
