Identify the triggers causing the barking in the first place and remove them. Never reward barking with attention, even unintentionally. Make your dog something else (sit, down etc.) and reward the quietness. Increase duration of the quiet time slowly. 

Read my blog about a client story and how we stopped a Jack Russel's excessive barking.

Find out the reason behind the pulling: is it fear? over excitement? If fear. avoid triggers (other dogs, motorbikes, people), if over excitement: provide outlets before the walks. Then once out and about: stop walking the moment the lead goes tight, and only move forward again once it's loose. Rewarding your dog for walking calmly beside you will reinforce the behaviour over time.

Puppies can begin learning from as early as 8 weeks old, making it the ideal time to build good habits. But it's never too late to start: dogs of any age benefit from training..

Basic commands can be learnt within 1–2 weeks of daily practice, but behavioural issues often require more time and patience. Every dog is different, and progress depends on consistency.

Step forward gently (this will naturally knock them off balance without ignoring them or punishing them) and ask for a wanted behaviour (sit, down etc.). Only reward the wanted behaviour. The key is is that everyone must do this, and I mean everyone. Otherwise your dog will keep playing the lottery: and one day he/she will win and someone will give them the attention they want/desire. 

Build your value. Start at home with no distractions: call your dog's name in a happy tone, and reward them generously every single time they come to you. Never scold them when they return, even if they took a while — you want coming back to always feel like the right choice.

Chewing is natural, so the goal is to redirect it onto appropriate items like toys or chews rather than trying to eliminate it entirely. Make sure your dog has enough mental stimulation and exercise, as destructive chewing is often a sign of boredom or anxiety.

Fear around other dogs is very common and can be improved significantly with gradual, controlled exposure at a pace your dog is comfortable with. A structured training plan can help them build confidence and learn that other dogs aren't a threat.

The core principles of positive reinforcement apply to all breeds, but some dogs are more food-motivated, more independent, or more easily distracted than others. I will adapt my approach to suit your dog's breed traits and individual personality.

It's a common concern, but there's an important distinction between a bribe and a reward: a bribe is offered before the behaviour is offered, whereas a reward comes after, reinforcing something your dog has already chosen to do. Over time, food is gradually phased out and replaced with praise, play, so your dog learns to respond reliably without always expecting a treat.
