Dogs Clothes

We got this two year old male German Shepherd and we’re planning on taking him to training classes but don’t have money yet. Here are some of our issues maybe somebody can give us some tips on training him that has experience with GS.

Obey in general and get the control over him as his owners?
Licking? We can’t use the nasty tasting stuff so is there any other tips?
Getting him to “Go to his place”
Shake?

Thank you! Anyone with experience with German Shepherds please answer.

I have a hairless Chinese Crested that gets cold very easily and also sun burns in the Summer. I also like to protect his skin from my Chihuahua’s sharp nails when they play. I try to keep a t-shirt or sweater on him at all times but I hate spending a lot of money on his clothes. Where can I find reasonably priced shirts on the internet? I typically buy him shirts from Target but I still find $8.00 to be excessive for a dog t-shirt…Any suggestions??

If you had $1000 to spend would you spend it on a puppy, Furniture and assessories, or clothes when you go shopping in a mall. why?
The furniture would be for my room, and i am a teen
the clothes would be for me
and with the money i would actually be spending it by buying a dog

Why is it that all these other business are having trouble, when compaines that make clothes for dogs or “baconaisse” are still in business?
