Hi!I've found doubling the weight at 4 months to be pretty accurate for small dogs. My dog was roughly 8 pound when I got him, I was told he was 5.5 months but based on when he lost his teeth I think he was more around 4 months. He is now 5 years old and 17lbs. How old is your puppy?
My dog is a poodle x pomeranian mix. He is leggy. I keep him very lean and he is all muscle. He stands around 14-16 inches high (can't remember exactly) and the length from his withers to his tail is about 14 inches. I'll return to this to post a picture when I'm not on my phone.
Thank you for the response! She is only 10 weeks old now. So I got her at 8 weeks and she was 3.5 lbs. I weighed her this morning and she is 5.2 lbs.
I'm looking forward to seeing a picture of your dog. If your dog is 17lbs, it'll be a great reference for me.
