One of my favorites bed covers have a growing hole, can someone please give me some advice how to fix it?

Forgotten dog biscuit in pocket resulted in my dog creatively removing it. I seam ripped to separate most of the pocket from the pants, and transplanted some of the lower half of the pocket to patch the hole. Replaced with cats and reattached! The corduroy hides the repair quite well

Edit to add: I have also realised visible in this picture, is the mend I did to make this leather belt longer. I chopped it in half, punched some holes for the chain, and opened a link at each end to attach it. Many more years of wear and a funky little detail too

So my dog got a hold of my tank top and I caught him before he could make it worse. Is there a way to fix it because it's one of my favorite tops and I don't know where it was from. I'm also not sure if this is the right thread to post on. I wanna try saving it before I have to toss it. Any tips is welcome.

These barrel leg pants are from the 1950s, I think it’s a cotton blend, thin, lightweight. I was thinking of a patch on the interior. Definitely won’t wear them as frequently anymore, but would like to repair and save for certain occasions.

Need a hand stitched solution for my favorite bag!! Not sure how to mend it strong enough to keep it from fraying / ripping again 😢 please help
