Do Rough Collies have high prey drive? Safe with bunnies & off-leash?

This is not likely a behavior that can be corrected but it can be managed with a lot of consistency and persistence. Sounds like Coop has a high prey drive which is instinct. Instinct is very difficult to overcome. Your best option is to try working with an in-home, professional dog trainer. They can give you the best advice after speaking to you and assessing Coop's behavior. I personally like Bark Busters as a company and it appears that they have a trainer in your area. I suggest you give them a call. I am pretty sure they do a free consultation. ( https://www.barkbusters.com/dog-training-seattle-north )

Trusty is a beautiful boy! The best thing you can for Trusty which is feeding a high quality dog food. Trusty does need to eat a large breed puppy formula. Stick with ProPlan or Royal Canin. I'm not sure the diet you are feeding is the correct one. It will say on the bag if it is intended for large breed puppies. He should eat this until he is 12 months old. Growth is genetic. A dog will not be any bigger than it's genes allow for. Growth in large breed dogs also needs to be slow to help prevent orthopedic conditions like dysplasia. Additionally, he will continue to grow (in height) until he is 12 months old. He will begin to fill out from 12-18 months of age (roughly). I hope this helps and please feel free to post any additional questions.

Some dogs no matter how you try cannot be trained off the leash. There are a lot of dangers when you have your dog off leash and it is recommended to keep them on. I would also recommend checking with local leash laws since most places you are not supposed to have them off leash. If you are able to do it and still want to I would recommend getting a trainer to work with you and with Reilly. Thank you for using Petco Pet Education Center, formerly Petcoach.

Border collies tend to have a high predatory drive, but some of them will do well with cats. Unfortunately there isn’t really a way to know this without trying. I would be very guarded an make sure they are not left alone together for quite a while until you know how they will react to the cat. Best of luck and I hope things go well! Thank you for using Pet Coach.

The best way to begin introducing a large dog to a cat is with a basket muzzle, on a leash, with extremely careful supervision. This is particularly true if you already know that Loki has a high prey drive. If Loki is a Border Collie, his intelligence may work for you or against you depending on his temperament. It is all about positive reinforcement in this sort of situation, and taking things slowly and carefully. I would not throw the kitten and dog together in the same room freely right away. Keep one of them in a crate and the other outside of it so they can see and sniff each other but not have any direct contact. After a couple of days, I would try the above thing I mentioned ( you will obviously require your mom's help with this ), making sure to have plenty of treats available on hand to reward any sort of positive response. If there is any negative response or act of aggression, do not punish Loki. Simply end the interaction and walk away for a few minutes, return, and try again. Punishment is ineffective in this instance and in most in my opinion. Once you are convinced after several sessions that Loki is not acting in an aggressive manner, try the same exercise but without the basket muzzle. Continue to do this until you are comfortable enough that they are buddies instead of foes. Hope this helps.

Beagles most certainly DO have a great sense of smell. Because of this, when off lead they can catch a scent that interests them and follow that rather than staying near you or listening to your commands. I would be nervous about letting most beagles of lead because of this. Before considering this, I would do a lot of training with Maverick in a fenced area practicing basic recall and recall with distractions.

That is a natural instinct for a Border Collie to herd or chase cats. You are going to have to do some training to see if you can teach him to ignore the cat. You should definitely teach him the "leave it" command to start as it may be very useful in this situation. Once he has mastered that command than you should have him on a leash while the cat is allowed to roam. Once your dog sees the cat than give him a command, like sit, leave it, etc. If he listens than give him a reward. Gradually let him get closer to the cat once he seems more relaxed and not paying attention to the cat. With persistence and patience, you may be able to teach him to leave the cat alone. I do not recommend leaving them unsupervised and make sure the cat has an area to escape at all times.
