I have 4 boston terriers and I free feed them, my food is always down I never pick it up and they are all the ideal weight.... I feed mine Nutro natural choice lamb n' rice my dogs do not over eat, they only get one treat a day and thats it... Boston's I find are gassy dogs :D
They should weigh between 10 and 24 lbs...
I think it all depends what your boston takes more after being the bulldog or the terrier. Tiva takes more after the bulldog and she is pretty bully and Junior takes more after the terrier so is alot more skinnier, their pups T-Bone and Dozer are a lil on the skinny side but not like their dad. Plus my 4 never sit still lol :D always on the go.
You can see my dogs ribs sorta, but you can feel them, my vet says they are a very nice weight. T-Bone weighs 28 lbs but No ounce of fat on her at all, she's kinda long in the legs but that prob because I fixed her too early at just 5 months same with Dozer and they both are that way. Wish I waited :(
