Panda is on the bigger size she is very long leged she weighs 24 lbs and Bear weighs 22lbs and my vet says they are a perfect weight. He also says it is better to keep them on the lighter side so it is better on the joints.

I was under the assumption mine would be about 20 pounds full grown. the vet laughed at me and mentioned she was 3 months and 11 pounds. She's almost 4 now.. almost 14 pounds now. Doc said he thinks she will be high 20's and he's even got some patients that are 35 and still perfectly healthy.

I've heard of teacup Bostons.. they don't weigh much at all. Like everyone says, just depends on the parents.

We got Opie when he was 11 months and he was only 9.9 pounds. His owner thought he was as big as he would get and that is why she gave him away. She shows BTs and said he was too small to show. Within 6 months he had grown taller and filled out to 14 pounds. At 2.5 he's about 15-16 pounds. Guess he was just a late bloomer.

at 4 months riley was 7.7 pounds. he's only suppose to grow to 10-12 pounds (as per the breeder) as the only breed the smaller weight class. it totally depends on the parents and as most people said as long as you cant see but feel the ribs your pup is health

Tank is 19 weeks and weighs about 10 lbs.

Now I'm really worried...Murphy is 6 months and 22 lbs! I guess I better start exercising my arms so I can lift him up when he's full grown. I wanted a max 20 lb BT...something we cannot control. I have seen small BT's, love them.

Molly is 13 pounds at 9 months old, but she is all legs... I have a feeling she isn't done growing!

Stormy was 7 pounds at 4 months, she is full grown at 15 pounds.

I was thinking I have a monster dog! Dexter is 3.5 mos and weighs 13lbs now. He picked up 3lbs from his last vet visit on Jan 4th and is growing fast. A friend of ours has Dex's little sister and she's only 7lbs but healthy just the same. I'm with Oliversmommy, I think it depends on the genetics

Pebbles just reach 10lbs and is now 19 weeks old.
