Dogs

We adopted a Golden Retriever puppy and everything went pretty smoothly. She's currently almost 5 months old. The in-home potty training went very well and very fast, she always does her business in a diaper-like sheet (sorry, I don't know the english term).

Now that she has her vaccines in order, she's ready to go outside. We've been trying for 1 week for her to get used to doing her business outside but it has been a frustrating experience. She doesn't feel comfortable doing her business outside and will only do it when she can't hold anymore. Her ability to hold poop is not that high so we have had some (not much) success with pooping outside but... we discovered that she can hold her pee for at least 4 hours. We haven't managed to get her to pee outside yet.

Things we tried:

• We take 3 walks a day, after every meal; Shorter walk on lunch time, longer walk on dinner time.
• Take the diaper sheets (both clean and dirty) outside, to create a sense of familiarity or smell. She ignores them completely
• Long walks with leash on grass or open field
• Long time in a doggy park, without leash and no other dogs and lots of water
• Walks with other friendly dogs that pee/poop frequently
• Praising other dogs when they pee/poop
• Play time with other friendly dogs in the doggy park
• Removing the diaper sheets inside, which causes to do her business on the floor without much of a thought
• Do a picnic on the grass and have her on a long leash to walk "freely"

We praise and reward her heavily when she poops outside and have no reaction when she does her business inside. She is still excited to go outside, I feel like she loves it there! Just doesn't enjoy doing her business there, I guess.

Any tips? Thanks a lot!
