WOW- Ok first - she is way too cute. Now, as far as potty breaking- Jake was horrible- It took us 6 mos before he was completely potty trained- And I remember the last accident-OF course we had company and he just went in front of every one- The husb pretty much lost his cool and Jake just clicked at that moment and he has never had an accident since. ( Husband didnt touch him, but verbally went off on him, guess that was enough)
Now the Pyrs- the girls, they were horrible- sounds like Ellie. Just random going, no definite time span etc, just squat. Part of it was thier age at the time, because as they got older they were able to hold it longer and got use to the "lets go outside" command.
Tug is a male- no problems- he holds it and goes out side- Absolutely NO accidents with him since he was about 7 weeks old.
I am wondering if the breeder kept her on a concrete or tiled floor- maybe that is why she feels that is where she is suppose to go? It would make sense. It will take some retraining to get her to go on the grass if that was the case. The leash is an excellent idea- She stays on the grass on the leash until she has gone potty- then she gets major praise and maybe a special treat that she only gets when she goes potty out side.
As far as the crating- she will eventually learn that it is her home, right now she is confused and probably just wants that human interaction. She probably had at least 8 siblings and if you think about it, puppies are very social creatures and take comfort in each other. She has been seperated from her siblings, is by herself, in a cage and without another living being to cuddle with, that is something that usually takes a little bit of time to get over as well. She will do it. She was probably miserable in her cage after having wet herself- so she may not ever do that again as well.
Feeding, I feed mine when they are hungry as puppies. I dont follow a certain rule. Tug is still eating several times a day. Some days he eats a lot more than others. But he is never allowed to go hungry for any reason. He seems to be doing ok with this. I dont normally free feed, but since he is a puppy- there is always a bowl full. Once we get past 1 year old- I will put the bowl away and feed morning and nite. The older dogs are enjoying this right now as well- but they dont over eat or take advantage. Find a good vet and realize, she will start growing past the bad times pretty quick. Sorry that this is so long.
