Each dog is different, but yes, doxies are difficult to housetrain as a rule. My Lexie would go outside if everything was perfect; no wind, no clouds, etc.
. Jack is 99.9% perfect as to housetraining. One time it poured for hours and he just could not hold it any longer. I understood that and could not blame him. Now that he's getting older, sometimes if it is cold outside, I have to carry him out to grass and then he will go and run right back in. Praise like crazy when they potty where they should, and maybe a tiny treat. I still praise Jack when he goes outside, for reinforcement, even though he's about 14! Just keep Eco-88 handy!
Hoomom who was blessed with Jack. RIP Sweet Cynda 6/3/10, loving Lexie 9/13/13 and Jack, 3/22/16.
