shes a puppy...and a lab puppy at that shes trying to play with little dog and not realizing how big she is (i have a similar problem with dozer, he has no idea hes a 11month old 85lb puppy and thinks hes 10lbs like ruby dog...)
by removing her and leashing her your not actually aressing the issue...
1: continue teling her no...but instead of leashng her and giving her a time out (afterall shes not actually doign anythign wrong...shes just playing) REDIRECT...grab a toy and YOU engage her, or take her for a walk or head into the back yard for some zoomie time or some training (mental stimulation is JUST as important as physical excersize) get involved...if shes chewing on the little og she needs more excersize/play time, your not going to slve this problem by putting her on a leash because that does nothing for the energy and probably just gets her more excited...but by reirecting her playing wiht her taking her for a walk ect your adresing the energy and refocusing the mind.
2: dont leave them alone unsupervised, shes a puppy and going to be large, accidents happen, nothing about what you said sounds agressive, BUT rough play with small breeds cna be dangerous and not worth the risk. so when you cant watch them seperate them either by tethering the lab to you (ie when your cooking ect) or crating ect.
for the poop eating, unfrotunatly very common in puppies, it could be food related bUT ive found most puppies will eat poop no matter wha tyou feed lol, 1 table spoon of Canned pumpkin (plain, no added sugar) will usually solve the issue (and is good for digestion)
also keep ontop od picking up the poop...cant eat it if you pick it up.
for health insurance...personally i dont do it...i DONT vaccinate regularly and have found these plans to be rather expensive for what they cover and will often even argu about coverage of things they DO cover
so instead i put whoever much the insurance would cost into a high yeild savings account and i keep a care credit card for emerencies...least with this method i dont have to worry about "is the insuarnce going to cover this" ect...
in terms of vaccines...
https://www.aahanet.org/PublicDocume...Guidelines.pdf
is the official current american veterinary regime...
personally my procedure goes like this:
Puppies:
5in1 (NO LEPTO NO BORDATELLA) at 8, 12 and 16 weeks
rabies at as close to 6 months as i can push it.
Teens:
5in1 booster at 1yr 2 months (no lepto no bordatella)
Rabies at 1 year since the initial rabies vaccine. (3 yr vaccine)
Adults:
Rabies every 3 years from the second vaccine
Titer test every 3 years. (thus far titers have come back clear with no need to revaccinate for anything else.
Lepto should ONLY be given to dogs that will have regular acess to standing water (ie kenneld/outdoor dogs, hunting dogs or dogs that spend alot of time hiking ect, as leptospirosis is spread by mouse and rat urine and most commonly contracted form drinking stanidng water that rodents have had acess too.
Lepto is also one of those vaccines that commonly causes reactions.
Bordatella is one thats quite controversial...in my especierience its USELESS....the vaccine has an effective life of 4-6 months only and only covers 3 of the current 7 (plus potentially more) strains of the virus...
some dog ay cares, grooming facilites and boarding kennels still require the bordatella (kennel cough) vaccine, in these cases and given no other option id give the bordatella vaccine no more than 2 weeks prior to boarding/grooming ect..) due to the shortlifespan youd have to give it every 4-6 months to be truly effective "full time" so useless to give as an annual...its somehting id only give is absolutly nessicary.
I also suggest never giving rabies and regular shots on the same day, the rabies shot is hard on the system so i like to give it at least a month between shots and rabies to avoid any kind of vaccinosis/reaction.
