As mentioned, in Australia no pets in the airport lounges, terminals, or aircraft. They have to fly in a special part of cargo, which is airconditioned. I have flown dogs all over the country, and international. Try and get direct flights, or the minimum of flights. The less stops the better.
I use frozen cubes with some electro lite with water, for their hydration - but not too much because of spillage. I had a dog fly from Sydney to Honolulu and was he glad to get out and have a piddle, (I did walk him heaps before the flight, and he did empty before the flight). Newspaper, for spills and something to cuddle into - don't use their blankets, as they will be destroyed by quarantine. It is okay to travel in cargo, but think of their comfort on arrival as well.
From far away, I can recommend CarolAnn near Columbus, OH, who might have or know someone who can satisfy your requirements. She has a rigorous qualification list for you to achieve, but expect it from any dedicated breeder. Good luck in your quest, and a long life for your new dog.
Sally is on the track, if you read the replies carefully you will find something that appears to have snuck in, but no where does it say to keep the dog outside, in the UK or most of the planet. You need to spend time with the Bs and see if you have affects on them as well as them on you. People including breeders, are protective of the breed, because rehousing a basenji is not always fun, because you do not know how they were treated, and it can take some months to get them relaxed again. That is why we are protective. Whatever you do, make sure you are liked by them, and you do not get affected by their traits. Good luck.
I agree with @tanza, there should never be any forced exercise until the bones 'set'. like a human baby until their skull sets, or a race horse are not allowed to race until they are two, so as to allow the bones to set. If they collapse because of their own induced tiredness, then that is okay, but never push them until they are well over 12 months, at least. You are doing right.
bad breath is a world of its own. It is a pre-cursor for a trip to the doggy dentist as the teeth become rotten from eating soft food. They need to chew the occasional bone, (this is a hobby horse topic of mine). The raw beef brisket bone is excellent for the dogs (RBBB). You have to be friendly with your meat purveyor (butcher to us in some places), as it comes in a length of about a 1 metre, (about three feet), and you get them to put it on the band saw and they will produce chunks of basenji size about 2 to 3 inches long (50 to & 75mm). The dogs love them, it keeps them occupied for a half hour, and it cleans their teeth without leaving a debris to shatter the windows like other bones. Excellent food. And natural, also.
I even had a bitch that hung on for 24 hours because it was raining. Eventually I coaxed her out and she kept very close to the walls and under the eaves to toilet. I put a collar on and lead, and walked her until she went in the rain, but as soon as she went, she insisted on going home, about a mile away, and she spent the rest of the morning getting that nasty water stuff of her.
Another time, it was really hot, and she was happy to paddle in the shallows of a major river. So they will get wet if there is a good reason.
I have contacted him, which is sometimes difficult because of shift-work, and he is ameniable to exporting one of his pups. he has a litter brother and sister, both full African. He will commence his planning early for 11months ahead, and the pups should be ready to fly around 10 to 12 weeks.
what are the quarantine restrictions like in Japan, because they are tough in Australia. There is quite a process to ensure quarantine requirements are met from here. Please send an email to me to firstname.lastname@example.org with any questions or clarifications you may have.
I hope that this perceived antic is past the worrying time. Most dogs will dump where they feel the need to leave their mark. Not a Basenji! No, no. The bitches will not crap in the open, so they always leave the patch and "go bush", making sure they do not leave their craps in the open, for anyone to find. If there is a thicket, all the better. The boys have similar behaviour, but every B is different. Some circle the wagon, some walk in a circle, and some take forever to find the right exact spot to have a crap. It is normal behaviour, so cater for their needs and your B will respect your thoughtfulness.
