Wow.. Then must have been scary.. Its great you were with him.. and it certainly sounds like your very responsible. Sometimes these things just happen.. Im glad that everything is fine..
I have read alot of scary things when it comes to collars and such. When I got our first Yorkie we use to use those nylon type harnesses and though nothing ever happened like that she just would never leave them alone and would always chew them badly. I was replacing them all the time. Yeesh!! Then I started making my own and they have never bothered with these. I like the clothing type harnesses because they serve two functions at once
They are safe and look cute too.. But thats just me.. I hope you find just the perfect thing for your little Mojo..
