I'm so sorry about your dog, really hope he is ok.
Can I clarify, as a new dog owner - so people do not put collars on their dogs AT ALL? I use a harness for walking on the lead, because I'm trying to teach him not to pull. But he has a collar with his ID tag on it, which he keeps on most of the time - I take it off at night when he goes to bed because he sleeps in a crate, but otherwise its always on. Is this a problem?
My husband isn't great at putting the harness on - mainly because he almost exclusively walks him off the lead, so its just getting him out to the car and then possibly from the car to place he's allowed off lead if its a car park. Should I force him to do it all the time? He does pull on the lead and it does choke him occasionally, which is why I bought the harness, but he hates having the harness put on and taken off so I think my husband doesn't bother if its only for a short period. What does everyone else do? (He's 21 weeks and a worker btw).
