Puppy showing agression towards older dog - HELP!

[Wendy]

Hi everyone - I'm Wendy and we have two dogs; Jenna is our 6yr old chocolate lab and Chloe is our 5mo multi-gen labradoodle. Jenna has never been around other dogs too much; but she is very sweet and doesn't have a dominant bone in her body. She is, however, pretty hyper. We brought Chloe home when she was 8wks and when the dogs were introduced, though Jenna was not "mean" towards Chloe, she freaked her out alot with her constant excitedness.
Now that Chloe is getting older & bigger she is becoming increasingly rough with Jenna. She will constantly jump on her and "bite and pull" anywhere she can grab, while growling at her at the same time. It's obvious Jenna doesn't like it, but she never really puts Chloe in her place. It's extremely frustrating having to constantly referee when they're together. We try to correct her by saying things like "No!", but it's not working. So to this point they don't spend a lot of time together. Except when they're outside because there is more to catch Chloe's attention.
Sorry this is so long, but we are at our wit's end. We had envisioned our two dogs hanging out, the best of of friends, and clearly this has not happened. Any suggestions would be so much appreciated!

I wish I had some words of wisdom for you. We have many dogs in the family (we have 3, my son has 2 and my mom has 1) and they all get along and always have but I will say that they do have a pecking order. The older ones seem to be indulgent with the younger pups. When our Springer was a puppy he was REALLY hyper and jumped all over the lab mix. The older one really put up with a lot. Now the Springer has settled down and we have Ned the labradoodle pup. He is always jumping on the older ones and chewing their ears etc. Our lab mix bites Ned's nose or steps on his paw when he is just too much, but our used-to-be-hyper Springer just doesn't know what to do but growl ineffectively. We pretty much let them be because I think they just have to determine their own rules and I have confidence that none of them will actually hurt the other. We don't allow Ned to eat anyone's else's food but he continually tries to eat the Springer's but never the lab mix's. He steals toys right out of the Sprnger's mouth but he and the lab mix play back and forth taking toys from each other. Lots of words but I guess what I am saying is that the hyper Springer is like Jenna and that maybe they just need to find their own way as long as you don't feel that either will actually hurt the other.

Rose our youngest would jump and bite Roy and some times Walt but never Lilly as Lil is the boss. In Roses case she just wanted somebody to play with her but she sure was not asking nice. They would either give in or walk away. If they were my dogs I would not interfere unless somebody was really getting hurt They will work it out and determine who is the boss. Sound like Cloe's getting attention but not the right kind, If she is being very aggressive I would remove her from the room if you can for 10-15 minutes while she calms down then bring her back in ,keep it consistent and she will get the idea that to stay with you she must be calm, plus sometimes with pups just like kids get over tired and get really hyper so with a time out she may realize she should rest.. She is just 5 months old and has a lot of learning to do yet. Maybe some extra excise would work off some of her energy. If Jenna was really annoyed she would let her know . Good luck puppy time can bee very trying but the do grow up.
