What was the protein content of your puppy feed?.What I would do is use a cheaper feed and deworm the pup .It would be more helpful if you had charted growth weight of the pup .Feel pretty sure the protein might be the culprit .Real easy to over grow muscle. Keep in mind that high price dose not make a feed good .I use puppy chow for about 12 weeks then switch them over to
Retriever. I use TSC Retriever mix the 25 % with the 21% 50/50 .When we have an abundance of surplus eggs .The dogs get 2 hard boiled eggs a feeding.I don't want to tell you to starve the pup . At a year old large breeds should only weigh about 75% of thier adult weight .By the time they are 2 they should have reached full bone and body mass .
Stay away from wet food .Compare feeds and slow down .For a while dry food and water might be your best choice.Never had a dog that I raised have rickets. I am either lucky are doing something right .Hope the pup is doing well today.
I use the TSC Retriever brand too. I also can chicken (buy leg quarters on sale) for the dogs. When we take animals to slaughter, I get the offal, heart, liver and can that too. When we process Cornish Cross chickens, I can the heart, liver, gizzards, necks, skin, fat and wing tips with rice for the dogs. Husband feeds the dogs, 1 quart split between 5 dogs, mixed with their kibble. I'm down to about a dozen jars of chicken and rice, leg quarters need to go on sale again!
