Why is my new dog anxious, growling, trembling, and hard to train?

Updated on September 23rd, 2025

Recently adopted a female Australian cattledog and American pitbull mix. She was okay initially but her behavior seems different every day. She starts getting anxious or hiding around night time from me. She was okay with my husband initially but now growls on him all the time. Donot even have treats from him or let him call her name. Also i have noticed head tremors 3-4 times since we got her which really scared me. She is also getting difficult to potty train.

Thanks for using Petco Pet Education Center, formerly Petcoach! These types of behavior can improve though this does require in person training with the help of a qualified dog trainer. I would encourage you to contact a dog trainer that can work with you and her in person to really take care of this behavior. The sooner these behaviors are dealt with, the more likely it is that you can improve and resolve them. Good luck and have a good night!

My dog goes crazy when strangers visit. How can I calm her down?

Thanks for using Petco Pet Education Center, formerly Petcoach! Almost any behavior can be resolved with training and behavior modification. I would highly recommend you consider contacting a local dog trainer who can work with you in person as that is needed. This should work but it will take time and persistence and of course a professional working with you both. Best of luck!

Why is my dog suddenly aggressive towards people and how to fix it?

Thanks for using Petco Pet Education Center, formerly Petcoach. My advice is to get professional help sooner rather than later. This type of behavior is often due to anxiety. I would strongly recommend talking to your vet about anti-anxiety/ behavior modification medication which can make a huge difference! Once the medication is on board, the fear-threshold is lowered, and learning can occur. At that point, working with a reputable trainer in your area is a must. Best wishes to you and Cooper.

My new rescue dog is extremely anxious and fearful. What can I do?

Wedo is adorable. I would consider getting a dog trainer or behaviorist They can see what he is doing and what the triggers are to make him scared. Then I would talk to your veterinarian about possibly starting medication to help Wedo with his anxiety. Thank you for using Petco Pet Education Center, formerly Petcoach.
