5 Puppy-Raising Mistakes That Backfire Later

Are you dealing with “normal puppy behavior,” or early warning signs of a bigger problem?
Some of the most common puppy behaviors, like fear reactions, growling over a toy or food, and mouthiness, can look harmless. But the way they’re handled early can be the difference between a phase and a serious problem, like reactivity or resource guarding that escalates into a bite.
In this episode, I’m joined by multi-certified dog trainer Ruth Hegarty of Creature Good Dog Training to break down five puppy-raising mistakes you’ll want to catch early. This is not about perfection. It’s about awareness.
BY THE TIME YOU FINISH LISTENING, YOU’LL DISCOVER:
• The early fear signs that can turn into adult reactivity
• Why letting mouthy behavior slide can create bigger problems later
• How to spot early resource guarding before it escalates
• The difference between playful chaos and reinforced hyper behavior
• Why waiting too long to socialize may backfire, even if you’re trying to keep your puppy safe
If you’ve been wondering whether something is “normal,” or whether you’re doing it right, this episode will help you zoom out and make smarter early decisions.

If you found this show because you're staring at your puppy and thinking, is this normal? Or you're asking yourself, am I really doing this right? You're in the right place. And today I'm joined by multi-certified dog trainer and the trainer behind Creature Good Dog Training, Ruth Hegarty. And Ruth's here because not only does she have the expertise to help us get off to a great start with our puppies, but she's also in the process of raising a new puppy herself. So all of this stuff is fresh in her mind and her experience. So Ruth, welcome back to the show.
Ruth Hegarty
Thanks, Amy. I'm happy to be here.
Amy Castro
Yeah, I'm glad to have you here. And I think this is perfect timing because like you said, it's puppy season before we know it. And you also have a puppy that you've been working with. So tell us about Archie a little bit.
Ruth Hegarty
Yeah, so I adopted Archie August 1st when he was 11 weeks old. He just turned nine months and first time I've ever adopted a puppy and not an adult dog. And he has really been a handful. So it's been fun and exciting and slightly overwhelming at times as well. Just everything you hear about raising a puppy.
Amy Castro (02:05.176)
And what's so funny too is in rescue, you can go six months and you forget what it's like to have them. And then you get a bunch in, you're like, holy moly, I didn't remember all this. And so I can only imagine for people who decide to get a puppy and it's been a couple of years, it can really hit you like a ton of bricks how much work it is.
Ruth Hegarty
The energy level for one and just the responsibility, the potty training, the socializing, teaching them their manners, supervising. I left my sweater on the couch last night and I go to put it on this morning and he had chewed the whole zipper.
Amy Castro
Of course he did. He was cleaning his teeth.
Ruth Hegarty
So, you know, and I'm a dog trainer and I know what to do, but you can't, you don't always think, especially when it's your own.
Amy Castro
Exactly, exactly. Well, and if you let your guard down for two seconds, they're into something. And I think that's why this episode is going to be helpful for people because it can be overwhelming and trying to figure out, what do I need to focus on? And so I kind of wanted to maybe hit some of the big five mistakes that you might be making and get those puppies off to a good start. So the first one that I wanted to talk about was fear because having had lots of puppies, even within a litter, there could be such a wide range of bold to fearful. And I think many puppy parents, like it's kind of cute when the puppy's scared of the fan or scared of the cat or scared of the whatever it might be, and that they're just gonna grow out of it. You know, true, false, or what's the reality there?
Ruth Hegarty
They're not going to grow out of it. And of course, there's a lot of nuance and there's a wide spectrum, but puppies, whether they're rescue puppies or purebred puppies, can be born more anxious, just like people, more anxious or more bold. What we want to be super mindful of is raising confident puppies to the best of our ability, because that's where you avoid problems down the road. Most of the reactive dogs I work with were under-socialized when they were young.
